In his TED talk Weller points out that latitude correlates with heart disease well. This study gets to clear out a lot of variables by sticking to the UK though so it is really valuable in testing the potential of UV without having to deal with as many social/environmental/etc etc factors. It would have been nice if the paper mentioned the world data that shows correlation between cardio vascular disease and latitude to help put this study into better perspective. To sum it all up: There is a world trend but the data is a bit messy. This study took a smaller chunk of the world and the results support the world trend and the data is much cleaner.
