Blue curves represented R-square. Orange curves represented the adjusted R-square. The relative weights of the significant features are shown on the bottom right of each plot. a Regression of data based on the dichotomy of BBS improvement in the M1. b Regression of data based on the dichotomy of BBS improvement in the M12. c Regression of data based on the dichotomy of PT improvement in the M1. d Regression of data based on the dichotomy of PT improvement in the M12. The subitems of BBS: item-1, sitting to standing; item-2, standing unsupported; item-3, sitting unsupported; item-4, standing to sitting; item-5, transfers; item-6, standing with eyes closed; item-7, standing with feet together; item-8, reaching forward with outstretched arm; item-9, retrieving object from floor; item-10, turning to look behind; item-11, turning 360°; item-12, placing alternate foot on stool; item-13, standing with one foot in front; and item-14, standing on one foot. BBS, Berg balance scale; PT, pull test; M1, 1-month follow-up; M12, 12-month follow-up.
