Search Methods for Systematic Reviews and Bibliographic Articles Can Improve: Responsibilities of Authorship Are Vast
Abstract
Certain types of scientific articles, including bibliographic articles, systematic reviews, and meta-analyses, require systematic search of electronic databases. Literature must be searched using clearly specified search terms, dates, and algorithms; article inclusion and exclusion criteria; and explicitly named databases. Search methods must be described in detail to allow reproducibility. In addition, responsibilities of all authors include contributing to study conception, design, data acquisition, analysis or interpretation; drafting or critically revising the work; approving the final version to be published; being accountable for the accuracy and integrity; being available to respond to queries including after publication; being able to identify which co-authors are responsible for which parts; and maintaining primary data and underpinning analysis for at least 10 years. The responsibilities of authorship are vast.
... Bibliometric is similar to systematic review in retrieving the literature [40], but they have low agreement rate regarding relevant literature and the purpose. While systematic reviews are seeking to respond to a very clear question based on good quality evidences, bibliometrics is rather a numeration of evidence without quality assessment. ...
... Bibliometrics often rely on the interpretation of quantitative details of publications such as main topics, authors, sources, most impactful authors, most impactful articles, and countries in a particular area in the existing literature. In this type of study, mapping techniques including graphical representations, tabulated forms, network diagrams, and so on are used to present results usually performing these with the assistance of softwares [39][40][41][42]. ...
... Overall, 13,720 papers were identified. After removing duplicates and irrelevant documents, only 19 papers [40,[43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] were found that were dealing with methodological issues. Also, we visited all reporting guidelines for review studies that are indexed in the EQUATOR [1]. ...
Background
A bibliometric review of the biomedical literature could be essential in synthesizing evidence if thoroughly conducted and documented. Although very similar to review papers in nature, it slightly differs in synthesizing the data when it comes to providing a pile of evidence from different studies into a single document. This paper provides a preliminary guideline for reporting bibliometric reviews of the biomedical literature (BIBLIO).
Methods
The BIBLIO was developed through two major processes: literature review and the consensus process. The BIBLIO started with a comprehensive review of publications on the conduct and reporting of bibliometric studies. The databases searched included PubMed, Scopus, Web of Sciences, and Cochrane Library. The process followed the general recommendations of the EQUATOR Network on how to develop a reporting guideline, of which one fundamental part is a consensus process. A panel of experts was invited to identify additional items and was asked to choose preferred options or suggest another item that should be included in the checklist. Finally, the checklist was completed based on the comments and responses of the panel members in four rounds.
Results
The BIBLIO includes 20 items as follows: title (2 items), abstract (1 item), introduction/background (2 items), methods (7 items), results (4 items), discussion (4 items). These should be described as a minimum requirements in reporting a bibliometric review.
Conclusions
The BIBLIO for the first time provides a preliminary guideline of its own kind. It is hoped that it could contribute to the transparent reporting of bibliometric reviews. The quality and utility of BIBILO remain to be investigated further.
... In addition to being published in the review section, many bibliometric articles are also published in the systematic review section (Gu et al., 2021;Zhu et al., 2022;Liu et al., 2024;Zhi et al., 2024). Bibliometrics is similar to systematic reviews in terms of searching the literature and can be used to study different and important areas of investigation and to obtain a general overview of the published literature (Lubowitz et al., 2023). Bibliometrics reviews all fully published articles in biomedical journals, including diverse research methodologies such as descriptive studies, observational studies, experimental studies, qualitative studies, and systematic reviews, thus illuminating the robustness of the available evidence (Manoj Kumar et al., 2023). ...
Introduction
Resveratrol (RSV) is a natural polyphenolic compound derived from a variety of plants that possesses a wide range of biological activities, including antioxidant, anti-inflammatory, antitumor, antibacterial, antiviral, anti-aging, anti-radiation damage, anti-apoptosis, immune modulation, regulation of glucolipid metabolism, inhibition of lipid deposition, and anti-neuro. It is therefore considered a promising drug with the potential to treat a wide range of diseases.
Method
In this study, using Web of Science Core Collection (WoSCC) and CiteSpace bibliometric tool, VOSviewer quantitatively visualized the number of countries, number of authors, number of institutions, number of publications, keywords, and references of 16,934 resveratrol-related papers from 2014–2023 for quantitative and qualitative analysis.
Results
The results showed that an average of 1693.4 papers were published per year, with a general upward trend. China had the most publications with 5877. China Medical University was the institution with the largest number of publications and the highest number of citations in the field. The research team was mainly led by Prof. Richard Tristan, and the journal with the highest number of published papers was Molecular. Dietary polyphenols, oxidative stress, and antioxidant and anti-inflammatory effects are the most frequently cited articles. Oxidative stress, apoptosis, expression, and other keywords play an important role in connecting other branches of the field.
Discussion
Our analysis indicates that the integration of nanoparticles with RSV is poised to become a significant trend. RSV markedly inhibits harmful bacteria, fosters the proliferation of beneficial bacteria, and enhances the diversity of the intestinal flora, thereby preventing intestinal flora dysbiosis. Additionally, RSV exhibits both antibacterial and antiviral properties. It also promotes osteogenesis and serves a neuroprotective function in models of Alzheimer's disease. The potential applications of RSV in medicine and healthcare are vast. A future research challenge lies in modifying its structure to develop RSV derivatives with superior biological activity and bioavailability. In the coming years, innovative pharmaceutical formulations of RSV, including oral, injectable, and topical preparations, may be developed to enhance its bioavailability and therapeutic efficacy.
... Bibliometric studies are similar to systematic reviews in the retrieval of the relevant literature [34], but they have different objectives than these. There is also a low rate of agreement between the two types of studies with regard to the retrieved literature. ...
The present study is an evaluation of published papers on machine learning as employed in mastitis research. The aim of this study was the quantitative evaluation of the scientific content and the bibliometric details of these papers. In total, 69 papers were found to combine machine learning in mastitis research and were considered in detail. There was a progressive yearly increase in published papers, which originated from 23 countries (mostly from China or the United States of America). Most original articles (n = 59) referred to work involving cattle, relevant to mastitis in individual animals. Most articles described work related to the development and diagnosis of the infection. Fewer articles described work on the antibiotic resistance of pathogens isolated from cases of mastitis and on the treatment of the infection. In most studies (98.5% of published papers), supervised machine learning models were employed. Most frequently, decision trees and support vector machines were employed in the studies described. ‘Machine learning’ and ‘mastitis’ were the most frequently used keywords. The papers were published in 39 journals, with most frequent publications in Computers and Electronics in Agriculture and Journal of Dairy Science. The median number of cited references in the papers was 39 (interquartile range: 31). There were 435 co-authors in the papers (mean: 6.2 per paper, median: 5, min.–max.: 1–93) and 356 individual authors. The median number of citations received by the papers was 4 (min.–max.: 0–70). Most papers (72.5%) were published in open-access mode. This study summarized the characteristics of papers on mastitis and artificial intelligence. Future studies could explore using these methodologies at farm level, and extending them to other animal species, while unsupervised learning techniques might also prove to be useful.
Background
Shoulder impingement syndrome (SIS) is one of the most common diseases of the shoulder and can be addressed with various therapeutic concepts. Orthobiological agents such as platelet rich plasma with a low side effect rate gain importance in the conservative treatment of SIS. Currently, the knowledge about success rate influencing factors, such as the growth factors (GF) concentration or acromion type, is limited. The aim of this study was to analyze the clinical outcome in the therapy of external SIS using autologous conditioned plasma combined with recombinant human collagen scaffold (ACP/STR) injection in comparison with a corticosteroid-local anesthetic (CSA) injection. Additionally, the influence of potential limiting factors such as GF concentration, age and acromial morphology was proved.
Materials and methods
This prospective pseudo-randomized trial recruited 58 patients with external SIS who received an ultrasound-guided subacromial injection either an ACP/STR or a CSA followed by physical therapy. Follow-up (FU) was performed at 6 weeks, 3 and 6 months. The outcome was assessed with Constant–Murley score, disability of arm, shoulder and hand score and simple shoulder test. The concentration of GF was measured using ELISA.
Results
During the FU, the improvement of outcome measures was observed with no differences between both groups. Shoulder force was significantly increased in the ACP/STR group (p < 0.01). We found no correlation between the amount of GF and age or gender in the ACP/STR patients. An acromion Bigliani type III predisposes for therapy failure (p < 0.001, OR = 56) in both treatment groups.
Conclusions
Patients with SIS benefit regarding to PROMs after both ACP/STR and CSA injection and physical therapy. Patients who received ACP/STR obtained superior improvement in force. The quantity of GF did not vary depending on the age, so that ACP/STR can be a treatment option for SIS in elderly patients with multimorbidity. The presence of an acromion type III seems to be a predictive factor for limited effectivity of injections in the clinical management of SIS.
Purpose
To identify and characterize the most cited publications in orthopaedic research related to posterolateral corner (PLC) injuries of the knee.
Methods
The Science Citation Index Expanded was queried for PLC injury articles. The 50 most-cited studies from 1976 to 2021 were selected. Article characteristics, including number of citations, citation density, year of publication, source journal, country of origin, article type, article subtype, and level of evidence, were analyzed.
Results
The number of citations for individual articles ranged from 47 to 205. The 50 most cited articles were published in 16 journals. Eleven of the 50 articles (22%) were published in Arthroscopy—The Journal of Arthroscopic and Related Surgery. The largest proportion of the articles (n = 22, 44%) were classified as clinical, with the rest classified as reviews (n = 15, 30%), and basic science research (n = 13, 26%). The most common level of evidence for clinical articles was IV (14/22, 63.6%). Nine countries contributed to the top 50 articles, with the majority published in the United States (n = 35, 70%).
Conclusions
In the last 20 years, papers published on the diagnosis and surgical management of PLC injuries have a high citation frequency. Future high-quality research is needed to establish best-practice guidelines for the management of PLC injuries due to the low overall level of evidence of existing clinical studies.
Clinical Relevance
This research provides a comprehensive list for practitioners and may help educators identify articles to include in the curriculum for residents and fellows.
To describe where papers come from in a systematic review of complex evidence. Method Audit of how the 495 primary sources for the review were originally identified.
Only 30% of sources were obtained from the protocol defined at the outset of the study (that is, from the database and hand searches). Fifty one per cent were identified by "snowballing" (such as pursuing references of references), and 24% by personal knowledge or personal contacts.
Systematic reviews of complex evidence cannot rely solely on protocol-driven search strategies.
Objective:
Network meta-analyses (NMAs) aim to rank the benefits (or harms) of interventions, based on all available randomized controlled trials. Thus, the identification of relevant data is critical. We assessed the conduct of the literature searches in NMAs.
Study design:
Published NMAs were retrieved by searching electronic bibliographic databases and other sources. Two independent reviewers selected studies and five trained reviewers abstracted data regarding literature searches, in duplicate. Search method details were examined using descriptive statistics.
Results:
Two hundred forty-nine NMAs were included. Eight used previous systematic reviews to identify primary studies without further searching, and five did not report any literature searches. In the 236 studies that used electronic databases to identify primary studies, the median number of databases was 3 (interquartile range: 3-5). MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials were the most commonly used databases. The most common supplemental search methods included reference lists of included studies (48%), reference lists of previous systematic reviews (40%), and clinical trial registries (32%). None of these supplemental methods was conducted in more than 50% of the NMAs.
Conclusion:
Literature searches in NMAs could be improved by searching more sources, and by involving a librarian or information specialist.
