Kaplan Meier plots stratified by three different groups of changes in frailty measured by the Short Physical Performance Battery (SPPB) from 6- to 36-months or the participant’s last study visit. We defined the three groups as “unchanged” (participants who had no change in SPPB frailty); “improved” (SPPB score improved by ≥1 point); and “worsened” (SPPB score worsened by ≥1 point).
