  1. a. Possibly selected observational case series
  2. b. Population includes some HIV non-infected individuals
  3. c. Outcomes reported at different time points for different patients
  4. d. Population derived from a study indirectly addressing question
  5. e. Outcomes not fully defined
  6. f. CD4 count not described or unusually low in some studies
  7. g. Population baseline characteristics described incompletely
  8. h. Significant loss to follow up
