DCA of the nomogram for predicting PONV in adult patients undergoing emergency surgery. The horizontal axis represents the domain probability value, and the vertical axis represents the net benefit rate. The light blue curve represents the assumption that PONV occurs in all adult emergency surgery patients. The black line represents the assumption that no PONV occurs in all adult emergency surgery patients. The red curve represents the nomogram constructed in this study. When the probability range of the domain is > 8%, the model has a high benefit for the prediction of PONV. DCA, decision curve analysis; PONV, postoperative nausea and vomiting
