Comparative detection of syndecan-2 methylation in preoperative and postoperative stool DNA in patients with colorectal cancer

Figure 3 Distribution of syndecan-2 methylation according to tumor node metastasis stage. The cycle threshold (C_T) values for each sample were calculated as 40-C_T. A higher 40-C_T indicates a higher methylation level of syndecan-2 (SDC2). If SDC2 methylation was not detected, it was expressed as 0. A: Preoperative (n = 123); B: Postoperative (n = 122). SDC2: Syndecan-2; C_T: Cycle threshold; TNM: Tumor node metastasis.
