Characteristics	Healthy (n=80)	Adenoma (n=85)	Cancer (n=155)	Chi square value/ t value	p Value
Gender				0.916	0.632
No. of male (%)	47 (23.7)	51 (25.8)	100 (50.5)
No. of female(%)	33 (27.0)	34 (27.9)	55 (45.1)
Age (yr)	51.19±12.53	55.02±10.88	58.17±12.12	9.188	<0.001
Hcy (μmol/L)	11.17±2.67^a	13.66±3.35^b	16.93±5.25^c	51.304	<0.001

Values with a different superscript letter (a, b, c) have statistically significant differences between the groups. P<0.05.
