PGF and colorectal carcinoma: Irrespective of whether early‐ or advanced‐stage CRC and with or without adjustment for age, sex, and BMI, our combined model still had the highest predictive power (unadjusted AUC: 0.780 for early stage and 0.805 for advanced stage; adjusted AUC: 0.797 for early stage and 0.794 for advanced stage, respectively) compared with the FOBT or serum PlGF level alone (Table 4).
