Table 2 Training cohort: Factors associated with in-hospital mortality: multivariate logistic regression with variable transformations

Factor	Estimate (95%CI)	OR (95%CI)	P value
Ln (Bilirubin)	0.61 (0.34, 0.89)	1.8 (1.4, 2.4)	< 0.001
1/PT	-47.2 (-67.3, -27.1)	0.09 (0.03, 0.26)1	< 0.001
WBC	0.07 (0.03, 0.11)	1.07 (1.03, 1.1)	< 0.001
MAP	-0.02 (-0.03, -0.01)	0.91 (0.86, 0.96)2	< 0.001

¹OR corresponds to 0.05 increment in 1/PT.

²OR corresponds to 5-unit increment in MAP. Ln: Natural logarithm; OR: Odds ratio; CI: Confidence interval; PT: Prothrombin time; WBC: White blood cell count; MAP: Mean arterial pressure.
