Thanks for sharing that.

I work with a different kind of data for a living, but still, I'll suggest using sites like that *very* carefully.

When you combine data from different sources and then try to extrapolate a new conclusion that wasn't the goal of the original studies, even a tiny error or wrong assumption can explode into seriously-wrong conclusions.

That happens even with full academic rigor like ethics boards and peer review, which is why you never trust the results of single study. When it's just a website that's convinced a single radiation oncologist to sit on its board and it's letting you generate arbitrary comparisons based on multiple independent variables, it might still be interesting, but I suggest swallowing it with a fistful of salt.

There's a very good reason that major research institutions like Mayo or the Cleveland Clinic don't offer this kind of thing.
