Ivermectin for COVID-19
4th treatment shown to reduce risk in August 2020
 
*, now known with p < 0.00000000001 from 100 studies, recognized in 22 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
3,800+ studies for 60+ treatments. c19ivm.org
Meta analysis including 17 of 100 studies (47 RCTs), finding significantly lower mortality with ivermectin. All seven outcomes favor ivermectin, while statistical significance is reached only for mortality. The conclusion is incorrect, authors find significantly lower mortality. Authors suggest lower risk of bias studies show lower effects, however their analysis is unreliable. For example consider Reis et al., authors give the study a perfect rating in risk of bias analysis, however this study not only has a very high theoretical risk of bias, but shows very high actual bias, randomization failure, blinding failure, and reports conflicting data that is impossible to be correct Reis.
7 meta analyses show significant improvements with ivermectin for mortality Bryant, Hariyanto, Kory, Lawrie, Nardelli, Zein, hospitalization Schwartz, recovery Kory, and cases Kory.
Currently there are 100 ivermectin for COVID-19 studies, showing 49% lower mortality [35‑60%], 29% lower ventilation [13‑42%], 38% lower ICU admission [14‑56%], 34% lower hospitalization [20‑45%], and 81% fewer cases [71‑87%].

Ivermectin under scrutiny: a systematic review and meta-analysis of efficacy and possible sources of controversies in COVID-19 patients

Background: We conducted a systematic review and meta-analysis to evaluate the efficacy of ivermectin for COVID-19 patients based on current peer-reviewed RCTs and to address disputes over the existing evidence. Methods: MEDLINE (Pubmed), Scopus, Web of Science, Cochrane library, Google scholar and Clinicaltrials.gov were searched for RCTs assessing the efficacy of Ivermectin up to 20 February 2022. A systematic review and meta-analysis of studies was performed based on the PRISMA 2020 statement criteria. Results: 19 and 17 studies were included in this systematic review and meta-analysis, respectively. There was no significant difference in progression to severe disease (log OR − 0.27 [95% CI − 0.61 to 0.08], I2 = 42.29%), negative RT-PCR (log OR 0.25 [95% CI − 0.18-0.68], I2 = 58.73%), recovery (log OR 0.11 [95% CI − 0.22-0.45], I2 = 13.84%), duration of hospitalization (SMD − 0.40 [95% CI − 0.85-0.06], I2 = 88.90%), time to negative RT-PCR (SMD − 0.36 [95% CI − 0.89-0.17], I2 = 46.2%), and viral load (SMD -0.17 [95% CI -0.45 to 0.12], I^2 = 0%). It is worth noting that, based on low-certainty evidence, ivermectin may possibly reduce mortality (log OR − 0.67 [95% CI − 1.20 to − 0.13], I2 = 28.96%). However, studies with a higher risk of bias were more likely to indicate positive effects on the efficacy of this drug, according to our subgroup analyses based on study quality. Conclusion: Ivermectin did not have any significant effect on outcomes of COVID-19 patients and as WHO recommends, use of ivermectin should be limited to clinical trials.
