So apparently you don't read either, you just attack the links, having no idea about the links?
Wow, now that is some REALLY amazing logic. Attack the message and the messenger.
I suppose I can educate you now, the way I educated your 2 buddies here:
A total of 3030 participants were randomly assigned to the recommendation to wear masks, and 2994 were assigned to control; 4862 completed the study. Infection with SARS-CoV-2 occurred in 42 participants recommended masks (1.8%) and 53 control participants (2.1%). The between-group difference was −0.3 percentage point (95% CI, −1.2 to 0.4 percentage point; P = 0.38) (odds ratio, 0.82 [CI, 0.54 to 1.23]; P = 0.33). Multiple imputation accounting for loss to follow-up yielded similar results. Although the difference observed was not statistically significant, the 95% CIs are compatible with a 46% reduction to a 23% increase in infection.
There, did you learn anything?
I learned it was one study and it didn't include the Delta variant which is far more contagious than the alpha virus and the Delta variant is the one we're all dealing with now. I also learned the "study" didn't include the most vulnerable to infection who could be protected by wearing a mask even though they've been vaccinated, ie immune-compromised people.
