I've seen data on that somewhere, and IIRC it's one of the factors that would be significant if the simple single bit "vaccinated or not?" didn't make everything else fade into the noise. Look at https://pubmed.ncbi.nlm.nih.gov/33932335/ for example. So and so many "per cent increase", while lack of vaccination causes "factor of x" increases and fuck the per cent.

In Finland it was over 50% last time I checked (BMI of 25+). Or it might've been deaths. In any case a significant number.
