†Rater scores are calculated only among participants who changed rater at the repeat assessment.
‡Time of day scores are calculated only among participants who changed time of day at the repeat assessment.
CGS, cognitive dual task gait speed; MGS, manual dual task gait speed; RCS, repeated chair stands; TUG, timed up-and-go; UGS, usual gait speed.
