  1. PWA people with AIDS, SMR sex and age-standardized mortality ratio, CI confidence interval; obs./exp.: observed/expected deaths
  2. a Conditions reported in any field of death certificates. Conditions reported in the same death certificate within the same ICD-10 group were counted only once; group of conditions with less than 10 observed cases among total PWA are not shown
  3. bBut I46 (i.e., cardiac arrest)
  4. cThe sum does not add up to total PWA because “other HIV transmission modes” were not reported
  5. dIncluding both male-to-male and heterosexual intercourse
