Figure 3. Hazard ratios and heterogeneity tests for primary and secondary outcomes among patients 65 years of age or older (solid circles) and those younger than 65 years of age (open circles).

CA = cardiac arrest; CHD = coronary heart disease; CHF = congestive heart failure; CV = cardiovascular; MI = myocardial infarction; PAD = peripheral artery disease; PR = procedure-related. *P value for heterogeneity (patients 65 years vs. patients <65 years).
