A recent cluster trial in Bangladesh randomized 600 villages into 300 treatment/control pairs, to evaluate the impact of an intervention to increase mask-wearing. Data was analyzed in a generalized linear model and significance asserted with parametric tests for the rate of the primary outcome (symptomatic and seropositive for COVID-19) between treatment and control villages. In this short note we re-analyze the data from this trial using standard non-parametric paired statistics tests on…

The Impact of Community Masking on COVID-19: A Cluster-Randomized Trial in Bangladesh
A cluster-randomized trial of community-level mask promotion in rural Bangladesh from November 2020 to April 2021 to identify strategies that can persistently increase mask-wearing and assess the impact of increasing mask-Wearing on symptomatic SARS-CoV-2 infections.
