The Cochrane Review's latest examination of a plethora of masking and other Covid intervention studies conducted before and during the COVID-19 pandemic should put the final nail in the coffin of the belief that widespread masking could have altered the trajectory of the outbreak.
- The analysis, which examined 78 studies featuring more than a million people around the world, found that community masking made "little to no difference" to either Covid death or infection rates.
The Cochrane Review is the “gold standard” in evidence-based medicine
- Includes a limited number of studies and has moderate power to detect small effects
- “Irrespective of the limitations of the study, its results indicate that the true impact of medical/surgical masks and N95/P2 respirators on the transmission of respiratory viruses is at best small”
