Changes in measured parameters from baseline to postintervention for patients in the active and sham groups.

Variable	Change; (postintervention—Baseline)	value
CRS-R total score
Active group		0.001^a
Sham group	1.0 (0-2)
GCS total score
Active group	1 (0-1.5)	0.014^a
Sham group	0 (0-1)
Latencies of N20 component (ms)
Active group		0.018^b
Sham group
N20-P25 amplitudes (μV)
Active group	1.360 (0.510-2.235)	0.011^a
Sham group	0.440 (0.115-1.265)
Change in BAEP grade (number)

Data are presented as deviation or median (interquartile range). Abbreviations: CRS-R: Coma Recovery Scale-Revised; GCS: Glasgow Coma Scale; BAEP: brainstem auditory-evoked potential. Significance level at value < 0.05; value refers to the results of the ^aMann–Whitney test and the ^bindependent samples -test.
