🚨n.b. #postprint 🚨

v10 of our #LivingReview is live on @qeios

We have reviewed 345 studies. 52 of sufficient quality for #MetaAnalysis to explore the association of #Smoking and #COVID19 #infection, #hospitalisation, #severity and #mortality.

qeios.com/read/UJR2AW.11 No dramatic changes from v9 posted in November.

Most studies from 🇺🇸, 🇨🇳 & 🇬🇧 but from 39 countries. 65% hospital based, 8% purely community. Median of 461 individuals per study.

Smoking remains poorly recorded, only 29% of studies categorise as current 🚬, former and never 🚭
