Summary of Findings | From a letter highlighting several limitations in the methodology and conduct of a systematic review on the efficacy of ivermectin treatment in COVID-19 patients published in 2021. The author of the letter highlighted several areas of concern: lack of clarity about whether the Jadad tool was utilized correctly or provided a valid assessment to measure risk of bias in studies; no GRADE assessment on the confidence of their findings as required by PRISMA; tests were not perfomed for normality using established methods prior to proceeding with the imputation; some outcomes and subgroup analyses were not outlined on the PROSPERO registration; 9 out of 18 of the included studies were pre-print articles and included retracted studies. |
