  2. *The top quartile of WC, WHR or WHtR in women (90 cm, 0.85 or 0.56) and in men (99 cm, 0.97 or 0.57) was used as the abdominal obesity group.
  3. †Hazard ratios (95% CI) from the Cox proportional hazards model using attained age as time-scale.
  4. ‡Hazard ratios (95% CI) from the Cox proportional hazards model adjusted for baseline smoking status, leisure-time physical activity, and cohort using attained age as time-scale.
  5. §Significance level = 0.05 for interactions between obesity and gender.
