Fig. 2

Calibration plots for each perioperative prediction model for people with kidney failure. The observed risk of 30-day cardiac or death events is plotted against the predicted risk in these calibration plots. The calibration plot for Model 1 is presented in Fig. 2a, Model 2 in Fig. 2b, Model 3 in Fig. 2c. The dashed line represents perfect calibration (with a slope of 1), and the solid line represents the lowess smoothed calibration curve. Each decile grouping of predicted risk is represented with an open circle along this calibration curve with accompanying 95% confidence intervals
