A distribution bar charts of the predicted probability of serum Ephrin-A1 in CRC patients and normal control. (a) The lowest concentration was 0.2119 ng/ml in normal control and the highest one was 3.6531 ng/ml in normal control in the test cohort. The concentration between 0.2119 ng/ml and 1.5051 ng/ml was divided equally for 20 sections, and the concentration higher than 1.5051 ng/ml was classified as one section. (b) The lowest concentration was 0.1726 ng/ml in normal control and the highest one was 2.8508 ng/ml in normal control in the validation cohort. The concentration between 0.1726 ng/ml and 1.3856 ng/ml was divided equally for 20 sections, and the concentration higher than 1.3856 ng/ml was classified as one section. CRC, colorectal cancer.
