Note: Multivariate model adjusted for age, sex and disease duration. Other variables were excluded due to non-significant univariate associations (ICU stay), population homogeneity (aetiology) or sample size limitations.
CRS-R, coma recovery scale-revised.cR2, contralateral late component; ICU, intensive care unit; iR2, ipsilateral late component; R1, early component.
