Commentary: What Can Masks Do? Part 2: What Makes for a Good Mask Study -- and Why Most Fail   [open html - 0B]

From the Document: "As noted in part 1 [hyperlink], not all facepieces designed to protect against respiratory diseases like COVID-19 [coronavirus disease 2019] are created equal, and they must be considered as only one tier in a hierarchy of protective steps. Here in part 2 we spell out why not all studies involving cloth face coverings or surgical/medical masks warrant equal consideration. We'll detail the necessary elements of a rigorous study and explore some recent studies that, though highly touted by both scientists and the lay press, fell quite a bit short of the ideal. Again, at the outset, we underscore that we are not 'anti-mask.' Rather, we are in favor of wearing the most protective type of facepiece for the setting--such as a non-fit tested respirator when spending more than a few minutes in a crowded, indoor space--and only in combination with other interventions."
