*A significant relationship between amputation category and denoted variable at .
Case mix groups (CMGs) are calculated from weighted admission FIM motor ratings: CMG 1001 (FIM motor greater than 47.65), CMG 1002 (FIM motor greater than 36.25 and less than 47.65), and CMG 1003 (FIM motor less than 36.25).
