But also in the last study the Ivermectin group was still a little over 1000 people which is enough to be statistically significant.
The first study is the one that really got my attention though, peer reviewed and had a very large sample size and showed with an extremely low dosage of Ivermectin(.2mg it showed 70% effectiveness as a prophylaxis. Nothing in the conclusion of the study: "Conclusion: In this large PSM study, regular use of ivermectin as a prophylactic agent was associated with significantly reduced COVID-19 infection, hospitalization, and mortality rates."
