Treatment effect of perindopril-based regimen in beta-blocker stratum: Forest plot. A Cox regression multivariate analysis was performed to calculate HRs and 95% CIs with adjustments for full model. The primary endpoint was the composite endpoint of cardiovascular mortality, non-fatal MI, and stroke. Among the 11,418 patients taking a beta-blocker, 5700 were randomized to a perindopril-based regimen and 5718 to placebo. P interaction was significant for all-cause mortality and CV mortality; all other p interactions are ns. CI, confidence interval, CV cardiovascular, HR hazard ratio, MI myocardial infarction, revasc revascularization, TIA transient ischemic attack
