  • a Detailed descriptions of antigens can be found in Materials and Methods.

  • b Odds ratios (ORs) and 95% confidence intervals (CI) for binding antibody multiplex assay (BAMA) mean fluorescence intensities were determined by logistic regression modeling controlling for log10 plasma viral load and peripheral CD4+ T cell count. Significant odds ratios less than 1 indicate that nontransmitters have higher responses than transmitters.

  • c Immune variables with unadjusted P values of <0.05 are in boldface.

  • d FDR, false discovery rate.
