Note: *Model 1 was univariate; Model 2 was controlled for age, sex, education, and living region; model 3 was additionally controlled for lifestyle factors (ever smoking and alcohol intake); and model 4 was further controlled for metabolic risk factors and cardiometabolic diseases (obesity, hypertension, diabetes, myocardial infarction, and stroke).
