🧵 TL;DR: In this school study, HEPA air cleaners showed little reliable impact on absenteeism, and air-quality improvements were limited during actual classroom use.

Here we go again with using observational data when it suits them.
This is particularly important here, because there’s a huge difference between observational data & trials on artificial sweeteners.

Good confidence that the NHS flu bed count will continue its fall this week. This counts positive tests (NOIDS causative agents report) and tends to be a decent leading indicator.

Sí, no creo que sea debido a una conspiración, tiene todo el sentido del mundo. Pero sigue siendo peligroso si no sabemos salir de ahí y todo lo vemos como una histórica batalla a muerte entre el bien y el mal (en la que somos los buenos).
