Hierarchical regression analysis of 12-month outcome prediction using the 3-month brain structure volumes with GCS and PTA as base model.

Models	R2	R2-change	Significance of F change
Base model	0.385
CortGM 3 months	0.515	0.053	0.023
Ventricles 3 months	0.467	0.005	0.494
Hippocampus 3 months	0.535	0.073	0.007
Lenticular ncl. 3 months	0.529	0.067	0.010
Rotterdam CT score	0.465	0.003	0.596

Base predictors: GCS, PTA duration (0 = PTA ≤ 2 weeks; 1 = PTA > 2 weeks), and age

CortGM predictors: GCS, PTA duration, age, and cortical GM volume at 3 months

Ventricular predictors: GCS, PTA duration, age, and ventricular volume at 3 months

Hippocampal predictors: GCS, PTA duration, age, and hippocampal volume at 3 months

Lenticular nucleus predictors: GCS, PTA duration, age, and lenticular nucleus volume at 3 months

Rotterdam CT score predictors: GCS, PTA duration, age, and Rotterdam CT score

CortGM, cortical gray matter; GCS, Glasgow Coma Scale; PTA, posttraumatic amnesia duration.
