DOI record: { "DOI": "10.1097/ms9.0000000000002762", "ISSN": [ "2049-0801" ], "URL": "http://dx.doi.org/10.1097/MS9.0000000000002762", "abstract": "<jats:sec>\n <jats:title>Background:</jats:title>\n <jats:p>The COVID-19 pandemic, resulting in approximately seven million deaths globally, underscores the urgency for effective treatments. Ivermectin, among several repurposed drugs, garnered interest due to its antiviral properties. However, conflicting evidence from observational studies and randomized controlled trials raised questions about its efficacy and safety.</jats:p>\n </jats:sec>\n <jats:sec>\n <jats:title>Method:</jats:title>\n <jats:p>This systematic review and meta-analysis followed MOOSE and PRISMA guidelines. Comprehensive searches were conducted in databases including Scopus, Embase, PubMed, and Web of Science up to April 2024. Data were extracted independently by two reviewers and analyzed using Comprehensive Meta-Analysis V3 software.</jats:p>\n </jats:sec>\n <jats:sec>\n <jats:title>Results:</jats:title>\n <jats:p>Across 33 studies encompassing 15,376 participants, ivermectin showed no significant impact on critical outcomes such as mortality [risk ratio (RR) 0.911, 95% confidence intervals (CI) 0.732–1.135], mechanical ventilation (RR 0.727, 95% CI 0.521–1.016), polymerase chain reaction conversion (RR 1.024, 95% CI 0.936–1.120), ICU admissions (RR 0.712, 95% CI 0.274–1.850), or hospitalization rates (RR 0.735, 95% CI 0.464–1.165) compared to controls. However, it significantly reduced time to symptom alleviation (standardized mean difference −0.302, 95% CI −0.587 to −0.018) and sustained symptom relief (RR 0.897, 95% CI 0.873–0.921). Adverse event (AE) rates were similar between the ivermectin and control groups (RR 0.896, 95% CI 0.797–1.007). Meta-regression indicated older age and diabetes as predictors of AEs.</jats:p>\n </jats:sec>\n <jats:sec>\n <jats:title>Conclusion:</jats:title>\n <jats:p>Despite its observed benefits in symptom management, ivermectin did not significantly influence critical clinical outcomes in COVID-19 patients. These findings highlight the importance of continued research to identify effective treatments for COVID-19, emphasizing the need for high-quality studies with robust methodology to inform clinical practice and public health policy effectively.</jats:p>\n </jats:sec>", "assertion": [ { "group": { "label": "Publication History", "name": "publication_history" }, "label": "Received", "name": "received", "value": "2024-06-24" }, { "group": { "label": "Publication History", "name": "publication_history" }, "label": "Accepted", "name": "accepted", "value": "2024-11-11" } ], "author": [ { "affiliation": [ { "name": "Dr Pinnamaneni Siddhartha Institute of Medical Sciences, Vijayawada, India" } ], "family": "Sai Y", "given": "Nithin", "sequence": "first" }, { "affiliation": [ { "name": "Baqai Medical University, Karachi, Pakistan" } ], "family": "Raheem", "given": "Abdul", "sequence": "additional" }, { "affiliation": [ { "name": "Universidad Anáhuac México, Av.
