Next, the diagnostic ability of these three biomarkers in discriminating melanoma from the control samples demonstrated favorable diagnostic value, with the AUC values of 0.985 (95% CI 0.951–1.000) in LTB4 (Figure 1G), 0.949 (95% CI 0.839–1.000) in CDHR1 (Figure 1H), and 0.911 (95% CI 0.720–1.000) in MARCKSL1 (Figure 1I). This evidence concerns the gene CDHR1 and melanoma.
