    “Overall, the studies on mask use during the COVID-19 pandemic highlight that face masking is an effective public health measure in controlling the transmission of SARS-CoV-2.”

    You correctly point out the Danish RCT found no significant benefit from community mask wearing.
    You repeat the JAMA network claim that the “second RCT involving 600 villages in Bangladesh with more than 340,000 residents found that wearing surgical masks in public places is associated with a modest, statistically significant reduction in symptomatic SARS-CoV-2 infection” which ignores the statistical re-analysis of the data revealing “the presence of unblinding, ascertainment bias, and bias-susceptible endpoints” in the initial analysis to such an extent that the “data is consistent with mask wearing having modest or no direct effect on COVID-related outcomes” 1

    Overall, studies to date have not demonstrated that community face masking was an effective public health measure in controlling the transmission of SARS-CoV-2, nor do they give us reason to believe community face masking will be effective in a future pandemic.
