Calibration curves for bleeding nomogram predictions in the training cohort (A) and Validation cohort (B). Notes The x-axis represents the forecasted bleeding risk, while the the actual diagnosed bleeding shown at y-axis. The diagonal dotted line showed an ideal model for the perfect prediction ability, and the solid line (bias-corrected line) represents the reality performance of the nomogram. The closer fit to the diagonal dotted line, the better prediction ability of the nomogram.
