EMB and infection: The major findings (based on a multivariate model including all six primary variables) were that gp70-V1V2-specific plasma IgG inversely correlated with infection rate (odds ratio 0.57, P=0.03, q=0.08) and that Env-specific plasma IgA was a direct correlate of infection rate (odds ratio 1.54, P=0.03, q=0.08) [32].
