"Largest study of its kind finds face masks reduce COVID-19":
Now, cue the geniuses who want to say the fact that masks don't eliminate the risk completely means that "masks don't prevent covid" and therefore are "useless."
More people needed to study probability and statistics in school...
"A randomized trial of more than 340,000 adults in Bangladesh finds that wearing face masks, particularly surgical face masks, significantly reduces COVID-19 in real-world settings. "
That's a decent sample size..."The results show that increased mask-wearing ?? the result of a community-level mask distribution and in-person promotion campaign ?? led to a significant reduction in the percentage of people with COVID-19, based on symptom reporting and SARS-CoV-2 antibody testing. The team tested both cloth and surgical masks and found especially strong evidence that surgical masks are effective in preventing COVID-19. In the study, surgical masks prevented one in three symptomatic infections among community members 60 years and older
...
While prior research has compared the rates of COVID-19 among people who wear masks and those who do not wear masks, the results of these comparisons may be skewed by the fact that people who choose to wear masks may adopt other behaviors that also reduce their risk. This study was designed to overcome this limitation by randomly assigning half of the communities to receive the mask promotion campaign, while the other half did not receive the campaign."
