ALT The need for a new review on masks was highlighted by a widely publicized polarization in scientific opinion. The masks section of a 2023 Cochrane review of non-pharmaceutical interventions (9) was—controversially—limited to randomized controlled trials (RCTs). It was interpreted by the press and by some but not all of its own authors to mean that “masks don’t work” and “mask mandates did nothing” (10). Cochrane’s editor-in-chief felt the need to state publicly that in Cochrane’s view, the review’s findings did not support such a conclusion (11). Some scholars were quick to question the review’s methodology, especially key flaws in the meta-analysis and omission of a vast body of non-RCT evidence (12–16).
