Results of a multivariable Cox proportional hazards analysis of progression-free survival for 149 patients with colon cancer, including patients’ gender, age at resection, UICC stage, and pDC infiltration. Significance was assessed using the Wald p value and is indicated by bold font in the table (*p≤0.05, ****p≤0.0001). When testing for proportionality, none of the parameters violated the proportional hazard assumption (all p values >0.05).
