The BPMS is a significant predictor of metastasis-free survival (MFS) after adjustment for clinical variables.

= 0.0073, χ2 = 7.2, df = 1). All available clinical data in a combined BrCa443/BrCa341 dataset was fit individually to Cox proportional hazards models. A) Clinical factors that were significant univariate predictors of MFS were placed into a full model along with the BPMS. B) An analysis of the variance (likelihood ratio test) comparing the multivariate model with and without the BPMS (L0 and L1 respectively) demonstrates the prognostic ability of the BPMS (p
