Note: Values shown mean (SD) or %.
Sample sizes for individual rows may be lower than the total due to missing values.
p-values were calculated using a t-test for continuous variables and chi-squared tests for categorical variables.
ADL = activities of daily living; BMI = body mass index; DBP = diastolic blood pressure; HDL = high-density lipoprotein; HS = high school; IADL = instrumental activities of daily living; LDL = low-density lipoprotein; SBP = systolic blood pressure.
