> “Conclusions and Relevance MMWR publications pertaining to masks drew positive conclusions about mask effectiveness over 75% of the time despite only 30% testing masks and <15% having statistically significant results. No studies were randomized, yet over half drew causal conclusions. The level of evidence generated was low and the conclusions drawn were most often unsupported by the data. Our findings raise concern about the reliability of the journal for informing health policy.”

I watch Dr Prasad on YouTube and he is pretty interesting IMO. He’s an oncologist but spends a lot of time analyzing medical studies.
