IgA-adjusted odds ratios of risk of HIV-1 infection (and p-values) based on data of Week 26 plasma reactivity with V1V2-scaffold antigens derived from two independent immunoassays.*

*Odds ratios are for every one standard deviation increase in the natural log-transformed OD (ELISA) or MFI (BAMA) and p-values for testing odds ratios equal to one are calculated using IgA-adjusted weighted logistic regression models as described in the text. The cross-reactivity score measures the average log10 response level across the four subtypes represented in the 6 V1V2 scaffolds, as defined in File S1.‡ELISA = enzyme-linked immunosorbent assay; BAMA = binding antibody multiplex assay.¥Data published in the original case-control study [3].†AP and LL denote production of comparable reagents by Drs. Pinter and Liao.§Reagent used in the original case-control study [3].
