Clinical utility of m6A levels in peripheral blood RNA, carcinoembryonic antigen (CEA), and carbohydrate antigen 199 (CA199) in diagnosing CRC. A Receiver operating characteristic curve and B cutoff value for m6A for patients with CRC and HCs; C receiver operating characteristic curves for m6A, CEA, and CA199 alone or together, and D cutoff values for m.6A, CEA, and CA199 in combination for patients with CRC and HC. HC: healthy control, CRC: colorectal cancer, CEA: carcinoembryonic antigen, CA199: carbohydrate antigen 199
