Univariate Cox proportional hazard models of the association of concomitant PTA at the time of PCI with clinical outcomes. Concomitant PTA was associated with higher risks of all-cause death, ESRD, amputation and PTA after discharge but was not associated with the risks of MACE, coronary revascularization, stroke or bleeding events in either the entire cohort or the PSM cohort. The concomitant PTA was significantly associated with a higher risk of CV deaths in the entire cohort but was not associated with the risk of CV deaths in the PSM cohort. *E-values indicate the HRs of unmeasured variables that could explain away the association between concomitant PTA and clinical outcomes and were estimated using the HRs and their lower limits of 95% CIs from the PSM cohort.
