TABLE 2.

Odds ratios of factors associated with 30‐day mortality (n = 10 763 hospitalized patients)

Factor	Unadjusted OR	Adjusted OR	95% CI	P‐value
Age (per 5 years)	1.25	1.16	1.13‐1.20	<.001
Male gender	1.41	1.24	1.06‐1.45	.008
Estimated risk of mortality within 90‐days after being hospitalized (per 5 percentage points) a	1.17	1.11	1.09‐1.14	<.001
Log white blood cell count at hospital admission	2.02	1.41	1.25‐1.58	<.001
Log alanine aminotransferase (ALT) at hospital admission	1.25	1.41	1.29‐1.55	<.001
Neutrophil to lymphocyte ratio (per quintile)	1.41	1.28	1.21‐1.35	<.001
Date of hospital admission (per month)	0.95	0.95	0.93–0.97	<.001

Note: Odds ratios were calculated from a general linear model specifying the binomial distribution and logit link and including hospital as a random effect.

^a Risk score is derived from an internally validated algorithm that is comprised of a range of variables predictive of mortality including socio‐demographics, medical history, recent laboratory values, and prior health care utilization.
