The adjusted differences are computed using linear regression. The adjustment variables are the values at admission (excepted for FAC), the age, sex and traumatic status (TBI or non-TBI). Crude estimates of the differences (i.e. without any adjustment) are given for comparison. All differences are given with 95% confidence intervals. CMD = cognitive motor dissociation; DOC = disorders of consciousness; GOS = Glasgow Outcome Scale; ERBI = Early Barthel Index; DRS = Disability Rating Scale; LCF = Rancho Los Amigos Levels of Cognitive Functioning; FAC = Functional Ambulation Classification Scale; mRS = Modified Rankin Scale.
