Construction of a nomogram prediction model for early postoperative stoma complications of colorectal cancer

Figure 1 Line chart model for predicting early postoperative complications in patients with colorectal cancer. PNI: Prognostic nutritional index; NRS: Nutritional risk screening.

Figure 2 Receiver operating characteristic curves of the training and validation sets for predicting early stomal complications after rectal cancer surgery. A: Receiver operating characteristic curves of the training set for predicting early stomal complications after rectal cancer surgery; B: Receiver operating characteristic curves of the validation set for predicting early stomal complications after rectal cancer surgery. AUC: Area under the receiver operating characteristic curve.
