When the samples were stratified for L1TD1 expression using the threshold where the ratio of the two Gaussian distributions was 10%, Kaplan-Meier analysis supported that the colon cancer samples with high L1TD1 expression had longer disease-free survival as compared to those with no/low L1TD1 expression (P = 0.038, Additional file 1: Figure S2C). The gene discussed is L1TD1; the disease is malignant colon neoplasm.
