p<0.001
Adjusted for age and BMI. Standardization based on multiplying the regression coefficient by the standard deviation of its corresponding predictor and dividing by the standard deviation of gait speed.
Partial R2 for adjusted model (i.e., R2 for grip and/or leg strength, conditioned on age and BMI being in the model)
p<0.001
Adjusted for age and BMI. Standardization based on multiplying the regression coefficient by the standard deviation of its corresponding predictor and dividing by the standard deviation of gait speed.
Partial R2 for adjusted model (i.e., R2 for grip and/or leg strength, conditioned on age and BMI)
Model 1 tested grip strength alone, model 2 tested leg strength alone and model 3 tested both measures simultaneously. Standardized coefficients indicate gait speed increases for every one standard deviation increase in grip or leg extension strength. * indicates p<0.001
