All models included eSPPB and BMI as the main predictor variables, the interaction between eSPPB and BMI, as well as the remaining covariates. Due to 2 missing eSPPB scores and 1 missing ICLV, 189 of the total 192 older adults were included in the analyses. Motion = number of brain volumes removed during motion correction. SE = standard error
