Table 4: Correlation between the degree of recovery from prolonged consciousness disorder and variables for 17 patients.

	Degree of recovery from PCD
Variable	r (Spearman correlation coefficient)	P values
Age	-0.39	0.13
Day of institution admission from injury	-0.29	0.26
mFAFM at first scanb	0.40	0.11
mFAWB at first scan	0.60	0.01
VsFA0.2 at first scan	0.56	0.02
Difference in mFAFM from first to second scan	-0.24	0.35
Difference in mFAWB from first to second scan	0.43	0.09
Difference in VsFA0.2 from first to second scan	0.67	< 0.01

mFAFM: mean fractional anisotropy value of the forceps minor; mFAWB: mean fractional anisotropy value for the whole brain; VsFA0.2: number of voxels with a fractional anisotropy value greater than 0.2 in the whole brain.
