In the last months, one of the first randomized control trial study on  masks  entitled "NORMALIZING COMMUNITY MASK-WEARING: A CLUSTER  RANDOMIZED TRIAL IN BANGLADESH" was published first as a NBER paper https://www.nber.org/papers/w28734  then as a Science article: https://www.science.org/doi/10.1126/science.abi9069  Newspapers and media outlets from all over the places celebrated it with  titles such as:   "We conducted the largest study on masks and covid-19: They work" - Washington Post  "Surgical masks reduce COVID-19 spread, large-scale study shows" - Stanford Medicine News  "First randomized trial on masking affirms efficacy, Yale study says" - Yale News  "Huge, gold-standard study shows unequivocally that surgical masks work  to reduce coronavirus spread" - Live Science  However, is the methodology and the data contained in the paper adequate  enough to back such claims?  Together with Pat Flynn we discuss the major flaws of this study and  raise some concerns on the way the media misrepresented it for political  purposes.  Additional reads: https://boriquagato.substack.com/p/bangladesh-mask-study-do-not-believe
