  1. Values are HRs with 95 % CIs of all groups compared with group 1. Groups 2 to 4 show higher risks of death than group 1. Patients were categorized into four groups on the basis of their risk scores
  2. CVD cardiovascular disease, HR hazard ratio, aHR adjusted hazard ratio, CI confidence interval
