The impact of ivermectin on COVID-19 outcomes: a systematic review and meta-analysis.
Article in Annals of medicine and surgery (2012), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: 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. Method: 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. Results: 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. Conclusion: 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.
