@GuyGadboisGuyG1 @Bob_Wachter @dr_kkjetelina The headline is misleading. The study actually showed about 2% chance of infection per hour with masks and much higher without.
Interestingly, the study also showed (not sure if mentioned in this article) that risk would be cut in half by keeping center seats empty.
@Guygadboisguig1@Bob_Wachter@dr_kkjetelina这个标题具有误导性。这项研究实际上显示，戴口罩每小时约有2%的感染几率，而不戴口罩的感染几率要高得多。
有趣的是，这项研究还表明（不确定本文是否提及）保持中间座位空着可以将风险降低一半。
