Association between OHS and unfavourable outcome (GOS) among survivors

	Model 1			Model 2			Model 3
		95% CI			95% CI			95% CI
OHS	OR	Lower	Upper	OR	Lower	Upper	OR	Lower	Upper
				1.0			1.0
Minor symptoms	1.7	1.4	2.1	1.6	1.3	1.9	1.6	1.3	2.0
Some restriction in lifestyle but independent	3.7	3.0	4.7	2.7	2.1	3.4	2.7	2.1	3.5
Dependent but not requiring constant attention	7.1	5.7	8.8	4.5	3.6	5.7	4.7	3.7	6.0
Fully dependent requiring attention day & night	24.1	19.8	29.4	12.9	10.3	16.2	13.3	10.4	16.9
C statistic for the model	0.78			0.83			0.83

Model 1: OHS

Model 2: model 1 plus GCS, pupil reactivity, major extra-cranial injury and age

Model 3: model 2 plus CT findings (petechial haemorrhages, obliteration of the third ventricle or basal cisterns, subarachnoid bleed, midline shift, non evacuated haematoma)
