Fig. 2From: Significant association and synergistic adverse prognostic effect of podocalyxin-like protein and epidermal growth factor receptor expression in colorectal cancerKaplan–Meier analysis. Kaplan-Meier estimates of 5-year OS according to combinations of PODXL and EGFR expression in cohort 1 (a), cohort 2 (b) and cohort 3 (c). Log rank p values correspond to pairwise comparisons of colorectal tumours with low expression of PODXL and EGFR with the other strataBack to article page
