Figure 1. — Graph of baseline, 6 and 12 months follow-up short physical performance battery (SPPB) and gait speed measures testing the effect of the trial intervention, treatment, and the interaction of intervention and treatment. ^aShort physical performance batter (SPPB) range from 0 to 12 points.

^bGait speed measured during 400 m walk test or proxy measures.

Note: Follow-up occurred at baseline visit, 6 months (6 m) and 12 months (12 m). Panels A/B: SPPB score by intervention arm and by treatment (unadjusted): Treatment × intervention (p = .298); treatment only (p = .478); intervention only (p = .002). Panels A/B: SPPB score by intervention arm and by treatment (IPTW-adjusted): Treatment × intervention (p = .443); treatment only (p = .541); intervention only (p = .012). Panels C/D: gait speed by intervention arm and by treatment (unadjusted): Treatment × intervention (p = .140); treatment only (p = .376); intervention only (p < .001). Panels C/D: gait speed by intervention arm and by treatment (unadjusted): Treatment × intervention (p = .244); treatment only (p = .179); intervention only (p < .001). All analyses conducted using analysis of covariance repeated measures.
