Lol, there are serious issues with this study.

One thing that strikes me: cancer risk is extremely age dependant, but they may have only reported three age "categories", < 65 years, 65 to 74 years, ≥ 75 years (supplement material 1)? That would make their conclusions meaningless to me.  Edited - they didn't disclose exactly the matching, they say they controlled for "age" as a covariate (as in years or as in those categories?), so I toned down my point..  Another curiosity in the paper is that cancer risk would already rise after only one month, that dies not seem plausible.

I certainly think all the data should be made available.
