Values are hazard ratios (95%confidence intervals) adjusted for age (except for subgroup analysis by age), hypertension (except for subgroup analysis by hypertension), diabetes mellitus (except for subgroup analysis by diabetes mellitus), dyslipidemia (except for subgroup analysis by dyslipidemia), chronic kidney disease (except for subgroup analysis by chronic kidney disease), smoking (except for subgroup analysis by current smoking), current alcohol intake (except for subgroup analysis by current alcohol intake), and regular exercise (except for subgroup analysis by regular exercise).
