 Izašlo istraživanje respektabilnog izvora koje kaže, manje-više, da maske i nisu neka baš prevencija -

Medical/surgical masks compared to no masks

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. Wearing masks in the community probably makes little or no difference to the outcome of laboratory‐confirmed influenza/SARS‐CoV‐2 compared to not wearing masks (RR 1.01, 95% CI 0.72 to 1.42; 6 trials, 13,919 participants; moderate‐certainty evidence). Harms were rarely measured and poorly reported (very low‐certainty evidence).

Nisam kliknuo na link, ali iz priloženog, deluje da pišu o hirurškim maskama, ne fpp maskama

 

Za hirurške znamo da nemaju istu zaštitu kao fpp

Kliknuo sam na link, i to je meta-studija, dakle smiješane su sve vrste maski (a nije sigurno ni da su uopšte bile nošene, niti nošene kako treba: gledano je samo da li je ljudima rečeno da nose maske vs nije rečeno.) Drugo, u celini radi se više o zaštiti od gripa, a svega par studija uključenih se odnosilo na kovid kao takav.

 

Za pohvalu autorima, oni sami kažu u zaključku:

The high risk of bias in the trials, variation in outcome measurement, and relatively low adherence with the interventions during the studies hampers drawing firm conclusions.

 

Možda je ovo stiglo u vesti i s toga što je glavni autor, Tom Jefferson, pomalo ekscentričan i voli da daje neobične izjave.
