      Ha! That is a bit basic.

      Their design doesn't really allow for the examination of their question regardless. What you'd need to do to see if smoking was protective is follow people through time, not just aggregate cross-sectional data in this way

      I don’t know about that. We’ve drawn conclusions about obesity and Covid from similar evidence.

      Sorry, yes, I didn't put that correctly. What you'd need to do is look at the whole at-risk population, whereas this study simply compares smoking rates in one group with a survey done 10 years ago. Can't really garner much from that!

      I mean, leaving aside the statistics for a second, can we really say much about comparing the number of smokers hospitalized today with COVID-19 to the mean rate of smokers in 2010? What would that even tell us?

      I don’t think it’s the 2010 date that’s the problem here.

      Take this study, for example (randomly Googled), comparing no. of obese patients in hospital with Covid to the obese population in 2014.https://www.thelancet.com/journals/landia/article/PIIS2213-8587(20)30160-1/fulltext …

      Yes that is equally terrible. Basic ecological fallacy

      Fair enough. I’d say it was crude but potentially useful. I’m not sure how else you’d do a case-control with this but by treating the cases as cases and everyone else as the control.

      You'd draw from the same population and try to match on as many factors as possible. Case-control 101!

          How would that work in practice? How can you match for factors when it’s factors you’re trying to identify?

          You match for basic things like age and gender and then connect enough information to correct for other factors in your analysis
