|Degree of recovery from PCD|
|Variable||r (Spearman correlation coefficient)||P values|
|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|
