Age, gender, and plasma homocysteine levels in the two groups studied, including the healthy controls, cases of rectal tumor.

Characteristics	Healthy (n=80)	Tumor (n=240)	Chi square value/t value	p Value
Gender			0.282	0.595
No. of male (%)	47 (23.7)	151 (76.3)
No. of female (%)	33 (27.0)	89 (73.0)
Age (yr)	51.18±12.53	57.05±11.77	3.681	<0.001
Hcy (μmol/L)	11.17±2.67	15.77±4.92	10.582	<0.001

Values with a different superscript letter have statistically significant differences between the groups. P<0.05.
