   The incorrect mathematical equations bias the results. Reanalyzing the data with the right equations show that masks, and N95s in particular, do prevent transmission.

   Here are a few highlights of the paper.

   1) Studies comparing N95s and surgical masks in healthcare workers ignore infections at home—outside study protocols. This effect is so large, a study claiming N95s give no more than 2X improvement, should instead say no more than 10X improvement, or even higher.
