Figure 3. Adjusted Analysis Comparing Components of Short Physical Performance Battery (SPPB) at 3-Month Follow-up in the Intervention vs Attention Control Arm Stratified by Baseline Frailty Status.

Adjusted measures of different components of SPPB score at 3-month follow-up among intervention and attention control group participants stratified by frail and prefrail status at baseline. Follow-up data are presented as least-squares means with SEs adjusted for baseline value, clinical site, age, sex, and ejection fraction category. Effect size represents the difference in least-squares means between the intervention and attention control groups. P for interaction (prefrail vs frail × intervention arm) was significant for 4-m walk score but was nonsignificant for all other outcomes. Error bars indicate 95% CIs.
