Results for COVID-OUT were reported in a presentation, however they are not currently available due to a news embargo. There were no statistically significant results for metformin, ivermectin, or fluvoxamine, except for a post-hoc metformin composite. Null results are expected based on the trial design and size (with metformin having higher power and a greater chance of showing a result despite the design).
We note that embargo and delay of clinical trial results during a pandemic is not consistent with a goal of minimizing mortality and morbidity, but is consistent with a goal of maximizing press for a trial designed to produce a null result.
Treatment was 14 days for metformin and fluvoxamine, but only 3 days for ivermectin.
Slides indicate that multiple imputation was used for outcomes.
