Figure 3. Cumulative incidence of repeat PCI for recurrent DES-ISR at 1-year follow-up for lesions with and without the four predictor variables identified in the logistic regression model.

A) Restenosis interval <6 months versus restenosis interval ≥6 months. B) Restenosis morphology: non-focal versus restenosis morphology: focal. C) Artery involved: left circumflex artery versus non-left circumflex artery. D) Vessel calcification: calcified vessel versus non-calcified vessel. CI: confidence interval; DES: drug-eluting stent; HR: hazard ratio; ISR: in-stent restenosis; LCx: left circumflex coronary artery; PCI: percutaneous coronary intervention
