Data are expressed as mean ± SD for univariate analysis and the mean ± SE for multivariate analysis. Univariate analysis was performed using one-way ANOVA, followed by a post-hoc Tukey comparison, and multivariate analysis was performed using analysis of covariance and adjusted for age, sex, and diabetes mellitus.
P < 0.05 compared with low tertile.
P < 0.05 compared with middle tertile.
HGS, handgrip strength; SPPB, short physical performance battery; STS5, five times sit-to-stand test; STS30, sit-to-stand for 30-s test; 6-MWT, 6-min walk test; TUG, timed up-to-go test.
