The pouch\u2010perineum distance of ultrasound (PPDU), the pouch\u2010perineum distance of invertogram (PPDI), and the rectum gas above the coccyx (RGAC) on the invertogram were hypothesized can serve as individual predictors.

The model's predicted accuracy was validated in the test cohort (AUC\u00a0=\u00a00.883).
