Conditional logistic regression model, accounting for matched pairs, describing odds for delirium/coma development in transfused vs. non-transfused patients

Characteristic	Adjusted Odds Ratio	Confidence Interval	p-value
Receipt of RBC transfusion (Ref: No transfusion)	8.94	2.8–28.4	<0.001
Delirium/Coma at time 0 (Ref: DFCF)	5.08	1.4–18.4	0.013
Developmental disability	4.02	1.2–13.6	0.026
PELOD-2 score	1.41	0.8–2.6	0.259
Male gender	1.17	0.4–3.2	0.755
Hemoglobin*	0.94	0.7–1.2	0.597

^*Odds ratio was calculated per 1 unit increase in hemoglobin (in mg/dL) at time zero.

[DFCF: Delirium-free and Coma-free; PELOD-2: Pediatric Logistic Organ Dysfunction-2 score (scores range from 0–33, with higher score reflecting greater severity of MODS at time 0)]
