Figure 4

Subgroup analysis for the relationship between concomitant PTA at the time of PCI and clinical outcomes. The HRs and CIs were derived from univariate Cox proportional hazard models constructed in the PSM cohort. *p values for the interaction between the categories. For CCI, the p values represent the interaction with the reference category (CCI ≤ 3). **Limb event is defined as a composite of amputation and PTA after discharge.
