  1. In the Cox regression model, perioperative variables p < 0.20 in the univariate analysis were considered. The first model is the perioperative model (second to fourth columns) and the second one is the postdischarge model (fifth to seventh columns). The c-index of the perioperative model was 0.697 before the bootstrapping method and 0.685 thereafter. The c-index of the postdischarge model was 0.691 before the bootstrapping method and 0.681 thereafter. B: regression coefficient, AHR: adjusted hazard ratio, STAI-T: trait anxiety subscale in the Spielberger State-Trait Anxiety Inventory, MACCE: major adverse cardiac and cerebral event.
