Table 2 Variables included in the multivariate logistic regression model for distinguishing between Gram-positive and Gram-negative infection

Variable	Prediction model
	β	Odds ratio (95%CI)	P value
Age	-0.026	0.951-0.999	0.040
IL-6 in pg/mL	-0.002	0.997-0.999	0.009
AST in U/L	0.001	1.000-1.002	0.070

AST: Aspartate aminotransferase; CI: Confidence interval; IL-6: Interleukin 6.
