Hazard ratios (HRs) and 95% confidence intervals (CIs) of major cardiovascular events among 13,887 men with no baseline history of cardiovascular disease (part A; Primary Prevention) and 754 men with a baseline history of cardiovascular disease (part B; Secondary Prevention) in the Physicians' Health Study II.
* Crude log-rank P=0.71 for 13,887 men with no baseline history of cardiovascular disease, and crude log-rank P=0.94 for 754 men with a baseline history of cardiovascular disease.
