Preoperative spectral computed tomography multi-parameter prediction of postoperative complications in colorectal cancer: A single-center retrospective cohort study

Figure 2 Nomogram for predicting postoperative complications in colorectal cancer patients. A nomogram for predicting the risk of postoperative complications. This model integrates clinical indicators including patient age, serum albumin level, portal vein tumor microvascular invasion (portal venous phase tumor normalized iodine concentration), tumor-nodes-metastasis stage, and intraoperative blood loss. Instructions for use: Locate the corresponding value on each variable axis, draw a line upward to the Points axis to obtain individual scores, sum all scores to get the total points, and finally read the predicted probability of complication occurrence on the risk of complications axis. NIC: Normalized iodine concentration; TNM: Tumor-nodes-metastasis; PV: Portal venous phase.
