Increased tumor necrosis factor receptor 1 expression in human colorectal adenomas

Table 3 Association between the measured biochemical parameters and the number of colorectal adenomas per person

	Control	≤3	≥4	P value
	(n = 34)	(n = 34)	(n = 28)
TNF-α (pg/mL)	5.63 ± 1.3	4.31 ± 1.9	4.95 ± 2.0	NS
sTNF-R1 (ng/mL)	1.57 ± 0.72	3.37 ± 0.93	4.05 ± 0.55	< 0.001
sTNF-R2 (ng/mL)	2.72 ± 1.15	3.13 ± 0.88	3.04 ± 0.95	NS

Values are expressed as the mean ± SD; P < 0.05 denoted significance. NS: Non-significant; TNF-α: Tumor necrosis factor-α; sTNF-R1/2: Soluble tumor necrosis factor receptor 1/2.
