Fig. 2From: Differing effects of beta-blockers on long-term clinical outcomes following percutaneous coronary intervention between patients with mid-range and reduced left ventricular ejection fractionCumulative incidence rates of the primary composite outcome for those with and without beta-blockers in the mrEF and rEF. There was no significant difference in the cumulative incidence rates of the primary outcome between the two groups in the mrEF (log-rank test, p = 0.137). There was a significant difference in the cumulative incidence rates of the primary outcome between the two groups (log-rank test, p = 0.003) in the rEFBack to article page
