The calibration plots for the adjusted model predicting recurrent revascularization. The x-axis represents the predicted adverse cardiovascular events risk. The y-axis represents the actual adverse cardiovascular events rate. The grey line indicates a perfect prediction by an ideal model. The red solid line indicates the performance of the predicting model, of which a closer fit to the grey line suggests better prediction. The adjusted model refers to the established risk model combined with the TyG index. Established risk model included age, BMI, Scr, bSS, rSS and insulin
