  1. Descriptive data are reported as mean ± standard deviation for continuous variables, as median (inter-quartile range) for ordinal variables and as counts for categorical variables. Patients’ best CRS-R index and sub-scores out of the repeated examination is reported. Univariate statistics are based upon the Mann–Whitney U test or χ2 test, as appropriate. p values was adjusted with the false discovery rate correction. Significant differences are reported in bold.
  2. Abbreviations: VS/UWS = Vegetative State/Unresponsive Wakefulness Syndrome; MCS = Minimally Conscious State; M = Male; F = Female; TBI = Traumatic Brain Injury; TPI = Time Post-Injury; CRS-R = Coma Recovery Scale-Revised.
