@_Kodos_ @humftydrumpfty @DrTomFrieden "Masks either work or they don't"
This is false. Every single study and every single intervention for that matter, has a degree of efficacy. In this case reduction by 19%, not "all or nothing" by 100%.
19% needs to be considered relative to the totality of conditions.
@_Kodos@humftydrumpfty@DrTomFrieden“口罩要么起作用要么不起作用”
这是错误的。针对这一问题的每一项研究和每一项干预都有一定的功效。在这种情况下，减少19%，而不是“全部或全部”减少100%。
相对于所有条件，需要考虑19%。
