Pre-exposure Prophylaxis With Various Doses of Hydroxychloroquine Among Healthcare Personnel With High-Risk Exposure to COVID-19: A Randomized Controlled Trial
et al., Cureus, doi:10.7759/cureus.20572 (preprint 5/17/2021)
Small PrEP RCT of low risk healthcare workers, showing no significant differences. Authors report that there was no hospitalization, ICU care, or death from COVID-19, however table 3 of the preprint shows severe events labeled as "requiring hospitalization". Symptomatology and disease severity results in tables 3 and 4 appear inconsistent. NCT04359537.
