Gene methylation detected in stool from colon cancer or non-cancer patients.

Methylation positivity and negativity based on methylation level at cut-off values; 0 for SFRP1, 0 for B4GALT1 and 8.53 for OSMR. M(+), Methylation positive.
aPatients with endoscopically normal colon (diverticulosis, diarrhea, polyps or bloody stool).
bPatients with colorectal cancer.
cPatients with adenoma.
dSum of methylation from SFRP1 and OSMR. Sum of methylation positivity was calculated by counting cases determined to be methylation-positive for at least one gene.
Sum of methylation negativity was calculated by counting cases determined to be methylation-negative for each gene.
Fisher's exact test was performed in enormal vs.CRC, and fCRC vs. AD; *P<0.05 was considered significant. n/a, not assesed.
