Kaplan-Meier analysis for Menacalc, pan-Mena and Mena11a in two primary breast cancer cohorts. Each cohort was divided into quartiles and disease-specific survival of the highest quartile of expression was compared to the remaining patient population. Inset is the histogram distribution of Menacalc or Z scores for each antibody. The number of patients in each group is shown followed by the number of patient deaths due to disease. Log-rank P-values are shown for 20-year follow-up. Only Menacalc scores are statistically significant in each cohort (P = 0.0004 and 0.0321, respectively).
