^aCox proportional hazard models were used to estimate the HR adjusted for age.
^bCox proportional-hazards models were used to estimate the HR adjusted for age, sex, education, smoking, BMI, the duration of diabetes, insulin use, and any history of heart disease, hypertension, dyslipidaemia, or stroke.
^cActive group includes participants who were intermediately or regularly active.
