The primary composite outcome was a composite of all-cause mortality, myocardial infarction, hospitalisation for heart failure and unscheduled coronary revascularisation. Person time and incidence rate is given in 100 person-years. Hazard ratios are given with 95% confidence intervals. The no beta-blockers group is the reference group.
