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).
