I know you’re being combative so it’s unlikely, but did you actually read both sources? One is a review of around 70 studies, before and during the pandemic, sonme unpublished. The other is a review of 5000 articles which found statistically significant results…
Fair point, I did misread that. But it seems you’re acting in bad faith with just one source again. Any search amongst published articles provide evidence for the efficacy and cost effectiveness of masks as a adjunct preventative measure. It seems rather like cherry picking to trust the one place that goes against the grain, no?
