@silas Cochrane mask study: 30JAN23
# Medical/surgical masks compared to no masks
Wearing masks in the community probably makes little or no difference to the outcome of influenza‐like illness (ILI)/COVID‐19 like illness compared to not wearing masks
# N95/P2 respirators
N95/P2 respirators compared with medical/surgical masks may be effective for ILI (low‐certainty evidence). Evidence is limited by imprecision and heterogeneity for these subjective outcomes.
