Kaplan-Meier estimates of occurrence of the primary end point for all patients and patients who underwent IVUS-guided stent implantation in IVUS-XPL. Cumulative incidence curves are for the primary end point of cardiac death, target lesion–related myocardial infarction, and target lesion revascularization. (A) Comparison of patients randomized to IVUS versus angiographic guidance. (B) Patients in the IVUS-guidance group, comparing those with versus those without stent optimization. HR, hazard ratio; IVUS, intravascular ultrasound; IVUS-XPL, Impact of Intravascular Ultrasound Guidance on Outcomes of Xience Prime Stents in Long Lesions; PCI, percutaneous coronary intervention.

Effect of intravascular ultrasound-guided vs angiography-guided everolimus-eluting stent implantation: the IVUS-XPL randomized clinical trial. aThere were 30 patients in the angiography-guided PCI group who underwent IVUS-guided PCI but they are not included in this analysis.
