  1. EU = HIV-1 exposed/uninfected individuals; Normals = random blood donors; LTNP = long-term nonprogressors; d.f. = degrees of freedom.
  2. a≅=p-values are uncorrected. Application of Bonferroni correction factor would multiply all p-values by 5 accounting for the 5 comparisons performed.
  3. bLTNP (a) was obtained from MACS (n = 53); LTNP(b) was obtained from LIR/NIAID (n = 32).
