Table 2. Threshold effect analysis of CRP on different types of HCC recurrence following curative hepatectomy using piece-wise linear regression.

	Crude OR (95% CI)	p-value	* Adjusted OR (95% CI)	p-value
ER
CRP≦2.1(mg/dl)	3.5 (1.7, 7.5)	0.001	3.5 (1.6, 7.6)	0.001
CRP>2.1(mg/dl)	0.8 (0.3, 2.1)	0.614	0.8 (0.2, 2.7)	0.703
LR	1.7 (1.2, 2.4)	0.001	1.8 (1.2, 2.5)	0.002

Crude: no adjustment.

* Adjusted: In ER group, characters of age, maximal tumor dimension, invasion to the portal vein and histological differentiation were adjusted. In LR group, characters of age, the maximal tumor dimension and tumor number were adjusted.
