You are correct on the citation (it's at the top of the page so I didn't think it needed to be re-cited). My read is the researchers found that in actual daily use with trained mask users there was no benefit in respiratory virus infection prevention from N95 over traditional surgical masks (laboratory testing doesn't mean people working in a laboratory, it means a controlled experimental test setting as distinct from actual real world usage). Are you reading a different conclusion from that paper? As I read it, their meta analysis strongly suggests that as far as viral respiratory diseases go, N95 masks add nothing but cost, discomfort, and security theater when compared with cheaper, more comfortable, and easier to wear surgical masks.
