A new paper claims kids masking associated with more daycare: Truth or Fiction?

A new paper has appeared Association of Child Masking With COVID-19–Related Closures in US Childcare Programs and finds that schools where all kids 2 and up wore a mask in May-June 2020 were 5.8% (ARR, 13% RRR) less likely to have 1 or more school closures due to COVID19 than schools that did not always have all kids 2+ wearing a mask in April 2020. The paper is hopelessly flawed.
