Waterfall plots. (a, b) Histograms of radiomic features for predicting PAS in the training and test sets. Samples with PAS are represented by blue bars, and samples without PAS (Non-PAS) are represented by orange bars. The y-axis displays the values of the R-score. (c, d) Histograms of radiomic features for predicting PPH risk in the training and test sets. Samples with PPH (+) are represented by blue bars, and samples with PPH(-) are represented by orange bars. The y-axis displays the values of the R-score
