Linear mixed effect model for ASPI values among TBI patients.

Fixed effect variable	Estimate	SE	pValue (likelihood ratio test)
Time from trauma	0.10627	0.02	<0.001
Platelet count	0.09221	0.01381	<0.001
COX inhibitor	−9.47869	4.23748	0.02583

Random intercepts: p < 0.001 [p value generated using (34)].

AIC value final model: 3,265.7.

Variables affecting ASPI values were compared across measurement time points. Variables that affected ASPI when examined graphically were included in the model. p Values were obtained using the likelihood ratio test, or as otherwise reported. Included random effects were random intercepts (subject ID), presented at the bottom of the table.

AIC, Akaike Information Criterion; ASPI, arachidonic acid receptor; COX, cyclooxygenase; TBI, traumatic brain injury.
