Multiple Logistic Regression Model for Number of RBC Transfusions and the Subsequent Development of Delirium in Transfused Patients

Predictor Variables	OR (95% CI)	p-value
Number of RBC transfusions	1.27 (1.04–1.56)	0.018
Age (> 13 years as reference)
< 1 year of age	1.47 (0.49–4.38)	0.478
1–3 years of age	0.96 (0.27–3.37)	0.608
3–6 years of age	1.52 (0.47–4.86)	0.470
6–12 years of age	1.06 (0.31–3.60)	0.777
Gender (male as reference)	1.71 (0.81–3.61)	0.163
PICU LOS (days)	1.01 (0.98–1.05)	0.458
Probability of mortality	7.57 (0.52–110.31)	0.139

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