Again kudos to @beenwrekt for taking the trouble to find out what the raw numbers actually were in the Bangladesh mask RCT that’s been used in court to support school mask mandates.
The difference between the raw data and what was presented in the Preprint is striking 1/

Here is the verbiage from the study —> an 11% relative risk reduction in symptomatic seroprevalence with the treatment group that was given surgical masks, 
The tables to support these words are here ..
The authors could have chosen to give us the actual raw numbers of symptomatic sero positives in treatment vs control, but instead we get interventional prevalence ratios and interventional coefficients ..
But they don’t.

Months later, when data / code is examined by @beenwrekt to c how many symptomatic positives were in the treatment and control groups .. the surgical mask group has 18 fewer cases, and the cloth mask group has 2 fewer cases
That’s the extrapolation.. argmin.net/2021/11/23/mas…

Surgical masks in the community are thought superior to cloth masks because out of 300k participants, investigators found an 18 case difference over 8 weeks, while cloth masks had a 2 case difference.
Unless somethings wrong with the data dump, it takes big time stones to confidently assert anything about masking 5 year olds based on this, even if Altoona, PA was similar to a village in Bangladesh.
Community mask 4 ever devotees will have to up their game. N95s with respirators may be the next hot Christmas toy little jack and Jill are going to find under their Xmas 🎄 tree this year.
