From: The downregulation of NCXs is positively correlated with the prognosis of stage II–IV colon cancer
NCXs can predict the prognosis of CC. According to the grayscale value of NCX expression in tumor tissue (tumor) and matched normal tissue (normal) calculated by WB bands, the ratios (tumor/normal) of NCX were obtained. Three group ratios of NCX1, NCX2, and NCX3 (n = 111; NCXs were identified by different curves) were used to draw ROC curves. The ROC curves used the NCX (NCX1, NCX, and NCX3) ratios to define the NCX cutoff values related to OS. The ROC curves of NCX1, NCX2, and NCX3 were used to predict the OS of 111 CC patients. The abscissa represents sensitivity, and the ordinate represents specificity. Numerical analysis of the area under the ROC curve showed significant differences
