  • a Based on the univariate aNAlyses (except for B*35 and B*53) shown in Tables 3 to 5.

  • b Based on all markers with an adjusted P < 0.10 in multivariable Model 1. NA, not applicable: dropped out of the fiNAl model when P > 0.05.

  • c Three HIV-1 seropositive patient groups (TPDs, transmission pair SCs, and discordant pair seropositives).
