Table 5. Cumulative incidence of repeat PCI for recurrent DES-ISR from 0 to 1 year for lesions with and without the four predictor variables identified in the logistic regression model.

Predictor	Predictor present (n/N, KM%)	Predictor not present (n/N, KM%)	Hazard ratio (95% CI)
Restenosis interval <6 months	93/387 (24.4%)	309/2,005 (16.4%)	1.62 (1.22-2.10)
Non-focal in-stent restenosis morphology	173/829 (22.4%)	229/1,563 (15.3%)	1.56 (1.28-1.85)
Vessel calcification	134/680 (20.9%)	268/1,707 (16.5%)	1.35 (1.09-1.63)
Left circumflex artery	147/700 (21.9%)	255/1,692 (16.0%)	1.44 (1.19-1.80)
Data are number of events with cumulative incidence (%) after accounting for competing risk of death. CI: confidence interval; KM: Kaplan-Meier
