Best performance for the different tests: Brier score = 0; the closest to 1, the worse the global accuracy. Performance for the AUC: 1 excellent diagnostic test and 0.5 bad diagnostic test. Best performance for Somers’ Dxy = 1; the closest to 1, the better the discrimination. Youden’s Index defines the optimal cut-point, which is the point at which the score performances are maximized. Slope: the closet to 1, the better the calibration. Intercept: the closest to 0, the better the calibration. Hosmer–Lemeshow goodness of fit: a non-significant P-value indicates a good test.
AUC: area under the curve; MR: mitral regurgitation.
