0.631, p = 0.001), and showed a strong trend toward superiority over the LPU‐radiomics model (AUC = 0.827 vs. 0.667, p = 0.070).
Although the validation cohort did not reach statistical significance, it showed a clinically meaningful improvement (ΔAUC = 0.117 and 0.136, p = 0.263 and 0.061, respectively).
The results demonstrated that the multi‐region fusion model achieved significantly superior diagnostic performance in the validation cohort compared with the single RGP model and the LGP model, and also showed a trend toward improvement over the single LPU.
