  1. Continuous variables are presented as mean ± SD, while non-continuous variables are presented as number (percentage). Weight was examined under standard conditions, i.e., after urinating and defecating with empty peritoneal cavity. Hypertension was judged by 140/90 mmHg or 150/90 mmHg (age ≥ 60). Carotid atherosclerosis was determined by ultrasound. BMI Body mass index
