Figure 6 shows the CHGA expression in normal controls and cancer patients (Figure 6A: colon cancer patients, Figure 6D: rectal cancer patients, Figure 6G: CRC patients), diagnostic ROC tests (Figure 6B: colon cancer patients, Figure 6E: rectal cancer patients, Figure 6H: CRC patients), and survival tests (Figure 6C: colon cancer patients, Figure 6F: rectal cancer patients, Figure 6I: CRC patients). The gene discussed is CHGA; the disease is colorectal carcinoma.
