Prognostic value of MibcMLP-generated risk scores in the internal validation set. HR and 95% CI for MibcMLP and other clinicopathological features to predict survival in (A) univariate Cox and (B) multivariate Cox analyses. MibcMLP model scores were converted to binary scores (high risk or low risk) using the median risk score of the training set as a cut-off. K-M survival curves for (C) the entire internal validation set and the following subgroups: (D) age ≥70; (E) male; (F) pT stage 3–4; (G) pN stage 0–1; (H) pN stage 2–3; (I) pTNM stage 1–2; (J) pTNM stage 3–4; (K) no lymphovascular invasion; (L) high histologic grade. ***, p < 0.001; **, p < 0.01; *, p < 0.05; HR, hazard ratio; CI, confidence interval.
