Could I ask who's calling? http://wallpapers.in.net/ sex wallpaper   A classical statistical error seems to exist in this analysis – the one of selection bias. It is a well known fact that more serious and complicated cases go to the more “established/reputed” institutions such as Johns Hopkins and Mayo et al. I don’t see any data that evaluates a patient’s condition before admission to show that these conditions are comparable across all hospitals surveyed.
