Habitual exercise, ≥ 3 hours/week (vs. rar align="center"ely/never)	0.81 (0.50–1.30)	0.38
Habitual exercise, 1–2 hours/week (vs. rarely/never)	0.99 (0.69–1.42)	0.97

Each hazard ratio (HR) and 95% confidence interval (CI) was adjusted by age and sex, while age was adjusted by sex and vice versa. Age per 1 standard deviation corresponded to 7.6 years.
