Comparison of Methylation Detection of CRC, Gastric Cancer and Other Gastrointestinal Tumors

Cancer Types	mSDC2 Rate (%)	p value	mSDC2 Rate (%)	p value	Total Positive Rate(%)	p value
CRC (61)	80.3 (49/61)		90.2 (55/61)		93.4 (57/61)
GC (N=37)	10.8 (4/37)	<0.001	29.7 (11/37)	<0.001	35.1 (13/37)	<0.001
Others (n=12)	0 (0/13)		21.4 (3/13)		21.4 (3/13)

Notes: mSDC2 rate refers to detection rate of methylated SDC2; mTFPI2 rate refers to detection rate of methylated TFPI2; total positive rate refers to integrated detection rate of methylated SDC2 and TFPI2. Others refers to other gastrointestinal tumors.
