Notional association of a risk factor with vascular, non-vascular, and all-cause mortality
Based on a doubling in the number of vascular deaths between each quintile of the risk factor (ie, 100, 200, 400, 800, 1600 deaths, respectively) but no difference in the number of non-vascular deaths (ie, 800 in each quintile), and with the overall percentages of deaths due to vascular and nonvascular causes (44% and 56%, respectively) similar to those in the Prospective Studies Collaboration.
