Patient characteristics of the study cohort.

Patient characteristics are shown for both the study cohort (n = 247) and the complete colorectal cancer series (n = 408). Patient selection was based on availability of FFPE tissues and available data for all four studied markers. The study cohort selection was representative for the entire colorectal cancer series. P-values represent the results of Student’s t-tests. For TNM stage, only tumor stage I-III of the complete patient cohort were compared to the patients in the study cohort.Patient characteristics of the study cohort.
