Outcome categorized by lowest GCS and FOUR score

Measurement	Score	N	Favourable outcome (GOSE ≥ 5)
GCS	3 4–14	36 (64%) 20 (36%)	13 (36%) 6 (30%)
FOUR score	0–3 4–16	7 (13%) 49 (88%)	0 (0%) 19 (39%)
FOUR score, eye response	0–1 2–4	49 (88%) 7 (13%)	16 (33%) 3 (43%)
FOUR score, motor response	0–1 2–4	38 (68%) 18 (32%)	14 (37%) 5 (28%)
FOUR score, brainstem reflexes	0–1 2–4	8 (14%) 40 (71%)	1 (12%) 18 (38%)
FOUR score, respiration	0–1 2–4	51 (91%) 5 (9%)	17 (33%) 2 (40%)

This table shows that a very low FOUR score carries a much worse prognosis than a GCS of 3. Restated, FOUR scores allow for a much finer distinction of patients with low levels of consciousness compared to the GCS. Data are presented as n (%). N, number of patients; GCS, Glasgow Come Score; FOUR, Full Outline of UnResponsiveness; GOSE, Glasgow Outcome Scale, Extended
