Comparison of prognostic performance by MVA and SnMVA following dichotomization based on median and optimal cutoff values. (A) OS and PFS curves for SnMVA (lower panels) and MVA (upper panels). SnMVA proved to be a more robust prognostic factor because its performance did not depend on which cutoff value was used or which type of survival was analyzed. (B) Forest plots of survival analysis for patient subpopulations based on predetermined clinicopathological characteristics.
