  1. Patient characteristics:
  2. N: number of cases; %: column percentage; CFR: AMI-CFR in %
  3. STEMI: ST-segment elevation myocardial infarction; NSTEMI: non-ST-segment elevation myocardial infarction; AMI NOS: AMI not otherwise specified.
  4. Level of care: community hospitals (labeled A) having no catheterization facility, intermediary hospitals (labeled B1) providing coronary angiography but no Percutaneous Coronary Intervention (PCI), and tertiary hospitals (labeled B2-B3) offering PCI and/or Coronary Artery Bypass Graft.
  5. Hospital characteristics:
  6. Minimum, Maximum: minimum and maximum number of observations per type of hospital
  7. Lower quartile, Median, Mean, Upper quartile: percentiles of the distribution of the number of observations per type of hospital
