Predictable responses will be to latch on to any weakness of the report in order to cling to anything to avoid embarrassemtn for being so horribly wrong and being exposed as having no real knowledge. The weaknesses of all studies are included in the body of the text so even a Google Doc can list them.
But remember....and this is key.....the burden of proof to wear masks in this setting is on the people pushing to impose mask wearing. And it should be noted that there was no strong evidence to do so. There NEVER was such evidence....not now nor back in 2020. This Cochrane Review shows it.
The key portion from your post:
"We included 12 trials (10 cluster‐RCTs) comparing medical/surgical masks versus no masks to prevent the spread of viral respiratory illness (two trials with healthcare workers and 10 in the community). Wearing masks in the community probably makes little or no difference to the outcome of influenza‐like illness (ILI)/COVID‐19 like illness compared to not wearing masks (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.84 to 1.09; 9 trials, 276,917 participants; moderate‐certainty evidence."
Moderate certainty level is quite strong from a Cochrane review in general, and specifically since there are so many variables in reporting and differing criteria between studies. BUT THE VERY CLEAR POINT IS THAT THERE WAS NEVER THE DATA TO SUPPORT THIS MASSIVELY INVASIVE IMPOSITION OF MASK WEARING ON THE PUBLIC - NOT NOW AND NOT BACK THEN. Fauci lied through his teeth as I have been saying. He initially admitted what he knew to be true before a meeting at the WH with BidenHandlers in late March 2020...then he completely changed his tune for political reasons. The medical community that spoke up was squelched.
