Figures 5B–D show that the AUCs of BRAT1-Abs for ESCC, GC, and CRC were 0.68 (95% CI = 0.6203–0.7489), 0.64 (95% CI = 0.5676–0.7229), and 0.62 (95% CI = 0.5560–0.6924), respectively. The AUCs of WDR1-Abs for ESCC, GC, and CRC were 0.68 (95% CI = 0.6233–0.7479), 0.68 (95% CI = 0.6131–0.7651), and 0.59 (95% CI = 0.5306–0.6646), respectively (Supplementary Figures 1B–D). The cutoff value, sensitivity, specificity, and P value are shown under the curves. The gene discussed is BRAT1; the disease is colorectal carcinoma.
