Figure 3 The nomogram for predicting the occurrence of CI-AKI after PCI in patients with NSTE-ACS. The final score (ie, total points) is calculated as the sum of the individual scores of each of the six variables included in the nomogram.

Figure 4 Calibration curve of the nomogram for the training set (A) and the validation set (B). The X-axis represents the overall predicted probability of CI-AKI after PCI and the Y -axis represents the actual probability. Model calibration is indicated by the degree of fitting of the curve and the diagonal.
