  3. 1Myocardial infarction is the reference dummy for both angina pectoris and congestive heart failure.
  4. 2Group 1 consists of catchment areas where the intervention center is the only hospital.
  5. 3Group 3 which consists of catchment areas with only local hospitals is the reference dummy for both Group 1 and Group 2.
  6. 4Group 2 consists of catchment areas with both intervention centers and local hospitals.
