The simplified systems for the assessment of consciousness that were studied, and their definition based on the GCS [8, 10, 12]

Scale	Value	Definition based on GCS
SMS	2	GCS motor component = 6
	1	GCS motor component = 5
	0	GCS motor component = 1–4
MGMR	2	GCS motor component = 6
	1	GCS motor component = 2–5
	0	GCS motor component = 1
AVPU	A	GCS total score = 15
	V	Not A, P or U
	P	GCS total score = 4–14
		And GCS eye component = 1–2
		And GCS verbal component = 1
		And GCS motor component = 1–5
