Note: TUG score and high-density lipoprotein cholesterol were log-transformed due to skewed distribution.

Model 1: adjusted for sex and estimated glomerular filtration rate.

Model 2: adjusted for model 2 plus body mass index, systolic blood pressure, chronic obstructive pulmonary disease history, dementia history, diabetes mellitus history, and cardiovascular disease history.

Model 3: adjusted for model 3 plus smoking habit, alcohol consumption, and high-density lipoprotein cholesterol.
