  1. aCI = confidence interval, HAART = highly active antiretroviral therapy, HR = hazard ratio, NR = not reported, OI = Opportunistic infection, OR = odds ratio.
  2. bArrows show directions of association with HSV-2; ‘?’ denotes borderline statistical significance or clinically significant differences not meeting statistical significance.
  3. cAdjusted for adenovirus 5 immunity, region, circumcision status, age, race, HLA group, trial intervention assignment (vaccine / placebo).
  4. dIncludes any ART (monotherapy, non-HAART combination therapy and HAART).
  5. eDefined as CD4 count <350 cells/mm3 or 18%.
  6. fAdjusted for baseline CD4 count.
  7. gAdjusted for age at HIV seroconversion, exposure category, sex.
