Abstract
Dr Collins and Ms Dillenbeck have indicated they have no potential conflicts of interest to disclose. BACKGROUND: We determined types of peer-reviewed articles that cited Pediatrics case reports and whether citations were "appropriate" or "inappropriate." METHODS: The 20 most highly cited Pediatrics case reports published between January 2011 and April 2016 were identified. All articles referencing these 20 case reports were analyzed for appropriateness of the citation. Appropriate citations referred to the original article specifically as a case report or cited the case report in support of general knowledge. Inappropriate citations used case reports to infer causation, support proof of mechanism, or were deemed irrelevant to claims being supported. Two authors independently coded all citations. RESULTS: These 20 case reports were cited in 479 articles (median: 24 citations per case report). In most articles (83.6%, n = 367), case reports were cited appropriately; in 53.4% (n = 196) of articles, a case report was specifically referred to, and in 46.6% (n = 171) of articles, the case report was used to support general knowledge. For inappropriate citations, in 63.3% (n = 50) of articles, case reports were used to infer causation; in 15.2% (n = 12) of articles, they were used as proof of mechanism of pathogenesis or treatment; and in 21.5% (n = 17) of articles, they were irrelevant. Case reports were most commonly cited in review articles (38.7%, n = 170) and original studies (31%, n = 136). "Original studies" were articles in which authors reported original data, excluding case reports. CONCLUSIONS: These results reveal that most citations of Pediatrics case reports are appropriate.

Pediatric case reports: assessing recommendations from journals' instructions to authors
Hospital pediatrics, 2014
Case reports (CRs) can be valuable contributions to medical knowledge and education. Objective assessments of publication potential and content recommendations for pediatric CRs are lacking. The "Instructions to Authors" provided by pediatric journals were assessed to determine journal characteristics, manuscript restrictions, and advice to writers. Pediatric journals referenced in the National Center for Biotechnology Information databases were identified by using the search term "pediatric." Further inclusion criteria were: active journals; currently indexed in the PubMed, Ovid, and/or Medline databases; and English as the primary language. Sixty-nine (52%) of 132 pediatric journals surveyed published CRs per their author instructions. The median 2011 impact factor for accepting journals was 1.28 (range: 0.47-5.44) compared with 2.40 (range: 0.59-5.50) for journals that did not publish CRs (P < .001). Twelve (67%) of 18 pediatric surgical specialty journals,...
Research methodology used in the 50 most cited articles in the field of pediatrics: types of studies that become citation classics
BMC Medical Research Methodology
Background One of the frequently used methods for assessing research trends and the impact of published scientific literature in a particular discipline is citation analysis. Journals may strive to improve their metrics by choosing manuscripts and study designs that are more likely to be cited. The aim of this study was to identify the 50 most-cited articles in the field of pediatrics, analyze their study design and other characteristics of those articles, and assess the prevalence of systematic reviews among them. Methods In December 2017, we searched Web of Science (WoS) for all articles published in the field of pediatrics. Two authors screened articles independently and in the further analysis included 50 articles with the highest number of citations. To avoid bias for scientific papers published earlier, the citation density was calculated. We also analyzed Journal Impact Factor (JIF) of journals where citation classics were published. Results The citation density in top 50 cit...
Citation classics in pediatrics: a bibliometric analysis
World Journal of Pediatrics, 2018
Background Citation analysis provides insights into the history and developmental trajectory of scientific fields. Our objective was to perform an analysis of citation classics in the journals of pediatric specialty and to examine their characteristics. Methods Initially, all the journals listed under the category of pediatrics (n = 120) were identified using Journal Citation Reports. Web of science database was then searched (1950-2016) to select the top-100 cited articles in the above identified pediatric journals. The top-100 cited article were categorized according the study design, sub-specialty, country, institutional affiliation, and language. Results The top-100 articles were published in 18 different journals, with Pediatrics having the highest numbers (n = 40), followed by The Journal of Pediatrics (n = 17). The majority (n = 62) of classics were published after 1990. The most cited article had citation count of 3516 and the least cited had a citation count of 593. The USA (n = 71) was the most commonly represented country, and 60 institutions contributed to 100 articles. Fifteen authors contributed to more than one classic as first or second author. Observational study (n = 55) was the commonest study design across all decades, followed by reviews (n = 12), scale development studies (n = 11), and guidelines (n = 11). Among the pediatric sub-specialties, growth and development articles were highly cited (n = 24), followed by pediatric psychiatry and behavior (n = 21), endocrinology (n = 15), and neonatology (n = 12). Conclusions The top-100 cited articles in pediatrics identify the impactful authors, journals, institutes, and countries. Observational study design was predominant-implying that inclusion among citation classics is not related to soundness of study design.
Pediatric publications in family medicine journals: quantity and content
Canadian family physician Médecin de famille canadien, 2005
To investigate the number and content of articles on pediatric medicine in family medicine journals. Computerized survey in PubMed of the abstracts of all papers published between 2000 and 2002 in four family medicine journals. Abstracts were classified as research or nonresearch. Papers dealing with pediatric medicine were further categorized by main subject area. Two North American family medicine journals and two British family medicine journals. Number and content of abstracts in family medicine journals: research or not research, describing children only or including adults. Of 1199 abstracts reviewed, 947 (79%) were from research articles and 252 (21%) from nonresearch articles. Of the research abstracts, 73 (7.7%) related to pediatric problems, and 28 (3%) related to both pediatric and adult problems. Of the nonresearch abstracts, 22 (8.7%) involved pediatric patients and 7 (2.8%) combined pediatric and adult populations. In all, nearly 11% of the articles related to pediatri...
<article-title aid="1466369">Reference Accuracy in Peer-Reviewed Pediatric Orthopaedic Literature</article-title>
The Journal of Bone and Joint Surgery (American), 2010
Background: Reference accuracy of articles published in the biomedical literature is determined by the presence of citation and quotation errors. A recent review demonstrated that the median citation error rate per biomedical journal was 39%, and the median quotation error rate per journal was 20%. Reference accuracy in pediatric orthopaedic articles has not been previously reported, to our knowledge.
Case Reports and Case Series in the Era of Evidence-Based Medicine
sobracil.org.br
Case reports and case series are important parts of the medical literature that continue to have their place in scientific journals. Frequently they are the first evidence for new therapies. Reports of cases and series are considered a low level of evidence their various arguments for and against their use in the incorporation of new treatments. Creative and critical use of these studies can increase a historical value by enriching the practice of medicine. The "methodology" used to report cases and the topics chosen to reflect our growing pragmatic approach in relation to evidence and arguments related to medicine and other health sciences.
Case reports and case series from had significant impact on medical literature
Journal of Clinical Epidemiology, 2005
Background and Objectives: Case reports and case series are often the first evidence of innovative treatment, but clinical trials need to follow to substantiate this evidence. The objective of this article was to evaluate case reports or case series describing innovative treatment concerning their impact. Methods: Case reports and case series (n < 10) from a high-impact journal, The Lancet, published from 1 January 1996 to 30 June 1997, were evaluated according to predefined criteria. To assess publication impact, Pubmed, Science Citation Index, the Register of Current Controlled Clinical Trials, and the Cochrance Controlled Clinical Trials Register were searched. Results: Sixty-four case reports and 39 case series were identified. They were cited in average 17 times (median 6,5; range 0-336). Twenty-Four follow-up trials were identified, nine in the register of current controlled clinical trials. Conclusion: Case reports and case series can be well received, and have significant influence on subsequent literature and possibly on clinical practice. Many were followed by clinical trials. Often, though, they report rare conditions for which trials may not be feasible, and more or less explicitly transfer established treatment into other conditions. Overall, there is a strong publication bias favoring positive results, and opportunity should be created for publication of follow-up reports.
Pediatric Research Challenge, Alignment with the National Research Agenda
Acta Medica Philippina
Research has always been one of the key areas given importance by the Department of Pediatrics. Barriers have previously stifled the conduct of research - inadequate or inaccessible funding, insufficient time due to academic responsibilities, and lengthy research application and publication processes have deterred potential researchers. Thanks to the tenacity of the faculty, the department has surmounted these obstacles and now continues to live up to the University’s expectations. The selfless dedication of the editors, peer reviewers, and researchers led to fruition and inspiration to replicate this achievement. The faculty believes that an unpublished study is close to not having done the study at all. The publication of this sponsored issue of the Acta Medica Philippina affirms the department’s determination to disseminate knowledge. The department supports its faculty in their bid to comply with requirements for professional advancement. This is a small step in aligning the dep...
The reporting requirements of case reports and adherence of case report reporting guidelines in medical journals: an analysis of the authors’ guide sections
Journal of Medical Case Reports
Background Owing to the growth of case reports and changes in the policy of journals in publishing this evidence, the need to standardize them is felt more than before. Therefore, in this study, the authors’ guide of medical journals indexed in the Scopus database that published most of the case reports has been analyzed to identify the reporting requirements and emerging case report types. Methods A total of 50 journals were selected from the Scopus citation database (the world’s largest knowledge base) that published most of the case reports. These and the authors’ guideline section on the types and requirements of writing case reports were analyzed by inductive content analysis. Results Most of the case reports were published in the fields of dermatology and surgery and general medicine. Reporting requirements in author’s guide are grouped in four categories: (1) reasons for publication or content value, (2) emphasis on the patient consent form and confidentiality, (3) emphasizin...
Tendencies in medical publications
Medicina Universitaria, 2015
Objectives: To describe the trends of research design in publications from high-impact medical journals. Methods: A cross-sectional, descriptive study was conducted by searching the 2011 electronic publications of the journals: New England Journal of Medicine, Journal of the American Medical Association, The Lancet, British Medical Journal, and Annals of Internal Medicine. Studies were classified as primary and secondary. The journal impact factor was taken from the Journal Citation Report website. Descriptive statistics were used to analyze and interpret the data. Results: We analyzed 1130 publications: 804 primary and 326 secondary studies, which represented 71.2% and 28.8% of the total publications, respectively. Among the primary studies, randomized clinical trials (30.4%) were the most prevalent, followed by cohort studies (21.9%) and case reports (9.0%). Conclusions: These findings can have implications in Evidence-Based Medicine programs. Literature review should focus on reviewing secondary articles first, then experimental studies and finally, observational studies.

Publication Trends of Pediatric and Adult Randomized Controlled Trials in General Medical Journals, 2005–2018: A Citation Analysis
Children, 2020
Policy has been developed to promote the conduct of high-quality pediatric randomized controlled trials (RCTs). Whether these strategies have influenced publication trends in high-impact journals is unknown. We aim to evaluate characteristics, citation patterns, and publication trends of pediatric RCTs published in general medical journals (GMJs) compared with adult RCTs over a 13-year period. Studies were identified using Medline, and impact metrics were collected from Web of Science and Scopus. All RCTs published from 2005–2018 in 7 GMJs with the highest impact factors were identified for analysis. A random sample of matched pediatric and adult RCTs were assessed for publication characteristics, academic and non-academic citation. Citations were counted from publication until June 2019. Among 4146 RCTs, 2794 (67.3%) enrolled adults, 591 (14.2%) enrolled children, and 761 RCTs (18.3%) enrolled adult and pediatric patients. Adult RCTs published in GMJs grew by 5.1 publications per y...
Duplicate Publication and Related Problems in the Pediatrics Literature
Global pediatric health, 2014
Objective. The aim of this study was to (a) determine the rate of redundant publication in the pediatrics literature and (b) to characterize these articles. Methods. Index articles in JAMA Pediatrics, Pediatrics, and the Journal of Pediatrics from 2010 were identified using PubMed. Possible redundant material from 2008 to 2012 were searched using the authors' names. Suspected duplicates were categorized into "duplicate publication" or "salami-slicing" (part of the index article repeated or continued). Results. Of the 1838 index articles, 39 (2.1%) were found to have some form of redundancy. Specifically, 45 articles were identified as salami-sliced, which corresponded to the 39 index articles. Fifteen salami-sliced articles did not reference the corresponding index article, 2 vaguely referenced the index article, and 28 had clear references to the respective index article. Conclusion. Salami-slicing was a common practice. Salami-slicing may be acceptable in c...
Publication of Randomized Clinical Trials in Pediatric Research
JAMA Network Open, 2018
Key Points Question What proportion of abstracts submitted to a major annual pediatric scientific meeting are subsequently published? Findings Among 129 phase 3 randomized clinical trials identified in this cohort study, 27.9% were not subsequently published, and 39.5% were never registered, with previous trial registration and sample size associated with greater likelihood of publication. Mean (SE) time to publication from study presentation was 26.48 (1.97) months, and there was evidence of publication bias among published studies. Meaning Further encouragement and follow-up are needed to ensure that the totality of evidence is made available to inform clinical decision making.
Reporting quality of abstracts and inconsistencies with full text articles in pediatric orthopedic publications
2023
Background Abstracts should provide a brief yet comprehensive reporting of all components of a manuscript. Inaccurate reporting may mislead readers and impact citation practices. It was our goal to investigate the reporting quality of abstracts of interventional observational studies in three major pediatric orthopedic journals and to analyze any reporting inconsistencies between those abstracts and their corresponding full-text articles. Methods We selected a sample of 55 abstracts and their full-text articles published between 2018 and 2022. Included articles were primary therapeutic research investigating the results of treatments or interventions. Abstracts were scrutinized for reporting quality and inconsistencies with their full-text versions with a 22-itemized checklist. The reporting quality of titles was assessed by a 3-items categorical scale. Results In 48 (87%) of articles there were abstract reporting inaccuracies related to patient demographics. The study's follow-up and complications were not reported in 21 (38%) of abstracts each. Most common inconsistencies between the abstracts and full-text articles were related to reporting of inclusion or exclusion criteria in 39 (71%) and study correlations in 27 (49%) of articles. Reporting quality of the titles was insufficient in 33 (60%) of articles. Conclusions In our study we found low reporting quality of abstracts and noticeable inconsistencies with full-text articles, especially regarding inclusion or exclusion criteria and study correlations. While the current sample is likely not representative of overall pediatric orthopedic literature, we recommend that authors, reviewers, and editors ensure abstracts are reported accurately, ideally following the appropriate reporting guidelines, and that they double check that there are no inconsistencies between abstracts and full text articles. To capture essential study information, journals should also consider increasing abstract word limits.
Incidental Findings in Pediatric Research
Journal of Law, Medicine & Ethics, 2008
Incidental research findings, as defined in this symposium’s consensus paper, are unexpected findings discovered in the course of research but “beyond the aims of the study.” These include findings generated by research methodology, such as imaging or genetic analysis, findings related to clinical screening for inclusion or exclusion, or direct observations of physical abnormalities or behavior. Decisions about managing incidental research findings involve important ethical considerations regarding a researcher’s obligations to provide care, minimize harms, and respect research participants’ wishes. When the research participant is a child, the triadic relationship between the researcher, child participant, and parent makes these considerations more complicated. (See Figure 1.)
A descriptive analysis of child-relevant systematic reviews in the Cochrane Database of Systematic Reviews
BMC Pediatrics
Background: Systematic reviews (SRs) are considered an important tool for decision-making. There has been no recent comprehensive identification or description of child-relevant SRs. A description of existing child-relevant SRs would help to identify the extent of available child-relevant evidence available in SRs and gaps in the evidence base where SRs are required. The objective of this study was to describe child-relevant SRs from the Cochrane Database of Systematic Reviews (CDSR, Issue 2, 2009).
Case Reports in Pediatric Dentistry Journals: A Systematic Review about Their Effect on Impact Factor and Future Investigations
Dentistry Journal
Background: The effects of publishing case reports on journal impact factor and their impact on future research in pediatric dentistry has not been clearly evaluated yet. Aim. To assess the relevance and role of case reports in pediatric dentistry. Methods: A systematic review (PROSPERO registration number: CRD42018108621) of all case reports published between 2011 and 2012 in the three major pediatric dentistry journals was performed manually. Data regarding citations of each report were acquired from the Institute for Scientific Information database available online. The authors analyzed information regarding citations (number, percentage, and mean) received by each case report and considered their relation with the 2013 journal impact factor. Results: Case reports accounted for almost sixteen per cent of all articles published between 2011 and 2012. The citation rate of case reports was generally low and the highest mean citation was 0.5. This review revealed that 6 (9.52%) case ...
