Disease-Free Survival Analysis for subgroups based on MMP-11 immunohistochemical score (A), Ki67 score (B) and both scores (C). A illustrates the survival probabilities of two groups of women: those with a MMP-11 immunohistochemical score greater than 50 (blue dashed line) and those with a score 50 or below (orange solid line). B illustrates the survival probabilities of two groups of women: those with a Ki67 score greater than 15 (blue dashed line) and those with a score 15 or below (orange solid line). C illustrates the survival probabilities of two groups of women: those with either Ki67 score greater than 15% or MMP-11 immunohistochemical score greater than 50 (blue dashed line) and those considered “low-risk”, with Ki67 score lower than 15% and MMP-11 immunohistochemical score lower than 50 (orange solid line)
