Calibration curve of the nomogram. The Hosmer–Lemeshow test yielded a nonsignificant statistic (p = 0.837). Calibration curves describe the model’s calibration in terms of agreement between the predicted probability of EMVI and observed positive proportion of EMVI. The dashed line named Ideal presents perfect performance, the other dashed line named Apparent presents the actual performance of the nomogram, and the solid line named Bias-corrected presents the actual performance of the nomogram after bias-correction
