Decision curve analysis for MR-EMVI, T-score and the nomogram of the EMVI assessment model. The black solid horizontal line at the level with Standardized Net Benefit 0 represents the assumption of all rectal cancer patients without EMVI. The grey solid line represents the assumption of all patients with EMVI. The green solid line represents the assumption that patients will be judged EMVI-positive if the positive probability obtained from MR-EMVI is higher than the threshold probability. The blue solid line represents the assumption that patients will be judged EMVI-positive if the positive probability obtained from T-score is higher than the threshold probability. The red solid line represents the assumption that patients will be judged EMVI-positive if the positive probability obtained from the nomogram is higher than the threshold probability. The decision curves showed that when the threshold probability is in a reasonable range, the nomogram provided the greatest net benefit when compared with the treat-all-patients approach, treat-none approach, and the MR-EMVI and T-score for predicting EMVI status of patients with rectal cancer
