  1. Patient characteristics are shown for both the study cohort (n = 254) and the patients with TNM stage I and II colon cancer as used for the statistical analyses (n = 121). Patient selection was based on availability of FFPE tissues, available data for all three markers, and information about the listed covariables. The study cohort selection was representative for the entire colorectal cancer series.
