The CDC just published a claimed “research article” that makes yet another claim by retrospective observation that “masks work.”
This study examined whether implementation of statewide mask mandates was associated with COVID-19–associated hospitalization growth rates among different age groups in 10 sites participating in the COVID-19–Associated Hospitalization Surveillance Network (COVID-NET) in states that issued statewide mask mandates during March 1–October 17, 2020. Regression analysis demonstrated that weekly hospitalization growth rates declined by 2.9 percentage points (95% confidence interval [CI] = 0.3–5.5) among adults aged 40–64 years during the first 2 weeks after implementing statewide mask mandates. After mask mandates had been implemented for =3 weeks, hospitalization growth rates declined by 5.5 percentage points among persons aged 18–39 years (95% CI = 0.6–10.4) and those aged 40–64 years (95% CI = 0.8–10.2). Statewide mask mandates might be associated with reductions in SARS-CoV-2 transmission and might contribute to reductions in COVID-19 hospitalization growth rates, compared with growth rates during <4 weeks before implementation of the mandate and the implementation week.
Note those four words: Might be associated with.
Isn’t it interesting that:
