Kaplan-Meier curves for clinical outcomes in all the patients (A, B) and the propensity-matched patients (C, D).
Kaplan-Meier curves for cardiac death and MACE in the patients treated with first-generation and second generation drug-eluting stents. MACE = major adverse cardiac event.
Fig 3.
Kaplan-Meier curves for cardiac death and MACE according to DES subgroup for all patients (A, B) and propensity-matched patients (C, D).
MACE = major adverse cardiac event; DES = drug-eluting stent; SES = sirolimus-eluting stent; PES = paclitaxel-eluting stent; EES = everolimus-eluting stent; ZES = zotarolimus-eluting stent.
Fig 4.
Comparative unadjusted hazard ratios of cardiac death for the DES subgroups out of all the patients between first-generation and second-generation drug-eluting stents.
CI = confidence interval.
