Table 6

Stepwise multiple linear regression analysis for variables associated with hospitalization period.

Variables	B	SE	β	T value	P value
Stone removal in early ERCP	7.467	1.223	0.418	6.107	< 0.001
Number of stones	0.568	0.203	0.192	2.792	0.006
CRP level	0.250	0.104	0.163	2.412	0.017

B: partial regression coefficient, SE: standard error, β: standardized partial regression coefficient, ERCP: endoscopic retrograde cholangiopancreatography, and CRP: C-reactive protein.
