Figure 1


Fig. 1 —Graph shows that each multivariate model had greater area under receiver operating characteristic curve (AUC) than model A (green) (Table 7), which included only MRI findings for lymph node metastasis (LMN). Model combining MRI findings for seminal vesicle invasion and LNM (model F) (red) had greater AUC than model A: 0.714 vs 0.633, respectively (p = 0.08). Model combining MRI findings for extracapsular extension and LNM (model G) (blue) had greater AUC than model A: 0.798 vs 0.633, respectively (p = 0.15). Model combining MRI findings for extracapsular extension, seminal vesicle invasion, and LNM (model H) (yellow) had greater AUC than model A: 0.813 vs 0.633, respectively (p = 0.11). Model combining MRI findings for extracapsular extension, seminal vesicle invasion, and LNM and Partin tomogram prediction of LNM (model I) (black) had significantly greater AUC than model A: 0.892 vs 0.633, respectively (p < 0.01).
