Table 2

Results of multivariate logistic regression model of predicting in-hospital death^*.

Variables	OR (95% CI)	value
Age (years)	1.10 (1.02–1.12)	0.002
Initial GCS	0.71 (0.51–0.97)	0.033
ISS	1.11 (1.01–1.22)	0.037
Lactate (mmol/L)	1.34 (0.83–2.16)	0.238
BD (mmol/L)	0.95 (0.80–1.14)	0.587
pCO2 (kPa)	1.50 (0.90–2.50)	0.123

Chi-square value = 48,406, df = 6, < 0.001, and Nagelkerke = 0.686.
OR: odds ratio; CI: confidence interval; ISS: Injury Severity Score; BD: base deficit; pCO₂: partial pressure of carbon dioxide; GCS: Glasgow Coma Scale.
