title: Data of top 50 most cited articles about COVID-19 and the complications of COVID-19

description: Background This bibliometric analysis examines the top 50 most-cited
 articles on COVID-19 complications, offering insights into the
 multifaceted impact of the virus. Since its emergence in Wuhan in December
 2019, COVID-19 has evolved into a global health crisis, with over 770
 million confirmed cases and 6.9 million deaths as of September 2023.
 Initially recognized as a respiratory illness causing pneumonia and ARDS,
 its diverse complications extend to cardiovascular, gastrointestinal,
 renal, hematological, neurological, endocrinological, ophthalmological,
 hepatobiliary, and dermatological systems. Methods Identifying the top 50
 articles from a pool of 5940 in Scopus, the analysis spans November 2019
 to July 2021, employing terms related to COVID-19 and complications.
 Rigorous review criteria excluded non-relevant studies, basic science
 research, and animal models. The authors independently reviewed articles,
 considering factors like title, citations, publication year, journal,
 impact factor, authors, study details, and patient demographics. Results
 The focus is primarily on 2020 publications (96%), with all articles being
 open-access. Leading journals include The Lancet, NEJM, and JAMA, with
 prominent contributions from Internal Medicine (46.9%) and Pulmonary
 Medicine (14.5%). China played a major role (34.9%), followed by France
 and Belgium. Clinical features were the primary study topic (68%), often
 utilizing retrospective designs (24%). Among 22,477 patients analyzed,
 54.8% were male, with the most common age group being 26–65 years (63.2%).
 Complications affected 13.9% of patients, with a recovery rate of 57.8%.
 Conclusion Analyzing these top-cited articles offers clinicians and
 researchers a comprehensive, timely understanding of influential COVID-19
 literature. This approach uncovers attributes contributing to high
 citations and provides authors with valuable insights for crafting
 impactful research. As a strategic tool, this analysis facilitates staying
 updated and making meaningful contributions to the dynamic field of
 COVID-19 research.
description: A bibliometric analysis of the most cited articles about COVID-19
 complications was conducted in July 2021 using all journals indexed in
 Elsevier’s Scopus and Thomas Reuter’s Web of Science from November 1, 2019
 to July 1, 2021. All journals were selected for inclusion regardless of
 country of origin, language, medical speciality, or electronic
 availability of articles or abstracts. The terms were combined as
 follows: (“COVID-19” OR “COVID19” OR “SARS-COV-2” OR
 “SARSCOV2” OR “SARS 2” OR “Novel coronavirus” OR “2019-nCov” OR
 “Coronavirus”) AND (“Complication”
 OR “Long Term Complication” OR “Post-Intensive Care Syndrome” OR “Venous
 Thromboembolism” OR “Acute Kidney Injury” OR “Acute Liver Injury” OR “Post
 COVID-19 Syndrome” OR “Acute Cardiac Injury” OR “Cardiac Arrest” OR
 “Stroke” OR “Embolism” OR “Septic Shock” OR “Disseminated Intravascular
 Coagulation” OR “Secondary Infection” OR “Blood Clots”  OR “Cytokine
 Release Syndrome” OR “Paediatric Inflammatory Multisystem Syndrome” OR
 “Vaccine Induced Thrombosis with Thrombocytopenia Syndrome” OR
 “Aspergillosis” OR “Mucormycosis” OR “Autoimmune Thrombocytopenia Anaemia”
 OR “Immune Thrombocytopenia” OR “Subacute Thyroiditis” OR “Acute
 Respiratory Failure” OR “Acute Respiratory Distress Syndrome” OR
 “Pneumonia” OR “Subcutaneous Emphysema” OR “Pneumothorax” OR

 “Otorhinolaryngology Complication” OR “Dermatological Complication” OR
 “Paediatric Complication” OR “Geriatric Complication” OR “Pregnancy
 Complication”) in the Title, Abstract or Keyword. A
 total of 5940 articles were accessed, of which the top 50 most cited
 articles about COVID-19 and Complications of COVID-19 were selected
 through Scopus. Each article was reviewed for its appropriateness for
 inclusion. The articles were independently reviewed by three researchers
 (JRP, MAM and TS) (Table 1). Differences in opinion with regard to article
 inclusion were resolved by consensus. The inclusion
 criteria specified articles that were focused on COVID-19 and
 Complications of COVID-19. Articles were excluded if they did not relate
 to COVID-19 and or complications of COVID-19, Basic Science Research and
 studies using animal models or phantoms. Review articles, Viewpoints,
 Guidelines, Perspectives and Meta-analysis were also excluded from the top
 50 most-cited articles (Table 1). The top 50 most-cited
 articles were compiled in a single database and the relevant data was
 extracted. The database included: Article Title, Scopus Citations, Year of
 Publication, Journal, Journal Impact Factor, Authors, Number of Authors,
 Department Affiliation, Number of Institutions, Country of Origin, Study
 Topic, Study Design, Sample Size, Open Access, Non-Original Articles,
 Patient/Participants Age, Gender, Symptoms, Signs, Co-morbidities,
 Complications, Imaging Modalities Used and outcome.
description: # Data of top 50 most cited articles about COVID-19 and the complications
 of COVID-19 This dataset
 contains information about the top 50 most cited articles about COVID-19
 and the complications of COVID-19. We have looked into a variety of
 research and clinical factors for the analysis. ## Description of the data
 and file structure The data sheet offers a comprehensive analysis of the
 selected articles. It delves into specifics such as the publication year
 of the top 50 articles, the journals responsible for publishing them, and
 the geographical region with the highest number of citations in this elite
 list. Moreover, the sheet sheds light on the key players involved,
 including authors and their affiliated departments, in crafting the top 50
 most cited articles. Beyond these fundamental aspects, the data sheet goes
 on to provide intricate details related to the study types and topics
 prevalent in the top 50 articles. To enrich the analysis, it incorporates
 clinical data, capturing information on patient demographics such as
 gender and age, prevalent clinical features, comorbidities, investigative
 approaches, common complications, and the clinical outcomes observed in
 the context of COVID-19 within the top 50 most cited articles. This
 comprehensive approach ensures a nuanced understanding of the multifaceted
 aspects encapsulated within the realm of COVID-19 research. The data was
 compiled by the authors and were manually reviewed. We would also like to
 mention that the data sheet is a summarisation of all the data that was
 collected. A consensus was reached to consolidate the data into a
 singular, concise sheet. This strategic measure was instigated by the
 inclusion of sensitive patient information, particularly concerning
 hospital identification details within specific studies. In an earnest
 commitment to upholding ethical standards and safeguarding against the
 inadvertent release of sensitive information to the public, a collective
 decision was made to disseminate a summarised iteration of the data. ##
