New pre-print study: 'Our main finding is that mask mandates and use are not associated with lower SARS-CoV-2 spread among US states'

A new pre-print study from the University of Louisville’s Damian D. Guerra and Daniel J. Guerra, Chief Scientific Officer of VerEvMed, has found that “mask mandates and use are not associated with lower SARS-CoV-2 spread among US states.”

You. Don’t. Say:

The first ecological study of state mask mandates and use to include winter data:

"Case growth was independent of mandates at low and high rates of community spread, and mask use did not predict case growth during the Summer or Fall-Winter waves."https://t.co/FAyieg02tJ pic.twitter.com/FVaDF112Q0

This really shouldn’t shock anyone:

It's just astonishing (not): "Mask mandates and use are not associated with slower state-level COVID-19 spread during COVID- 19 growth surges." https://t.co/Pb52pLJksQ

Note, this is a pre-print so the usual caveats apply:

Just ran across a pre-print making its way across the right-wing twitter saying masks don't work and someone doing epidemiology who isn't an epi. Methods look quick and broad. I'm not sure it's saying anything about masks. https://t.co/yvOss7JINx
