Computed tomography 3D reconstruction and texture analysis for evaluating the efficacy of neoadjuvant chemotherapy in advanced gastric cancer

Figure 4 Analysis of decision curve analysis curve of prediction model. The graph compares the net benefit of three treatment strategies: Prediction model, treat all, and treat none. Before a risk threshold of 0.5, treating all patients shows the best results; after that, the prediction model performs better. The treat-none strategy maintains near-zero benefit throughout. This helps select the optimal treatment approach based on patient risk levels.
