5 mL/kg	1.38 (1.07–1.78)	0.014
10 mL/kg	1.90 (1.14–3.17)	0.014
15 mL/kg	2.61 (1.21–5.63)	0.014
Age (> 13 years as reference)
< 1 year of age	1.87 (0.47–7.47)	0.940
1–3 years of age	1.54 (0.33–7.14)	0.612
3–6 years of age	3.68 (0.83–16.32)	0.112
6–12 years of age	2.45 (0.55–10.93)	0.552
Gender (male as reference)	1.38 (0.60–3.17)	0.456
PICU LOS (days)	0.99 (0.97–1.02)	0.501
Probability of mortality	1.22 (0.08–19.24)	0.889

Probability of mortality was determined by the Pediatric Index of Mortality-3 score.
