alt Hacker NewsI see quite the opposite. On the left side of the plot, for countries with the lowest cvd rates, there is a whole range of dosages for statins. In other words, countries with low and high statin usage have low death rates from cardiovascular disease.
Diet & lifestyle? Leftmost Low statin has some high fish intake high veg diet. But probably not low salt. Far right has some high salt, high smoking rate econs. I selected AU, NZ and UK to compare as high health budget, high statin use. average Western diet to AR,UY which have good health systems, meat dominated, lower statin and see a weaker but present horizontal separation.
Maybe I'm being to optimistic about the signal. I do tend to a default position of belief in western medical science consensus and it tends to "take statins if old" according to "big statin" funded pop science at least.
