Brief Report: Bacterial Vaginosis and Risk of HIV Infection in the Context of CD101 Gene Variation.
Article in Journal of acquired immune deficiency syndromes (1999), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhether bacterial vaginosis (BV) and CD101 immunoglobulin-like (Ig-like) variants independently increase HIV risk through mucosal inflammation is not well understood. We evaluated whether the impact of BV on HIV acquisition in women differs by the presence or absence of candidate CD101 Ig-like variants.
methodsWe used data from 2 studies of HIV serodiscordant couples in east (Kenya, Tanzania, and Uganda) and southern (Botswana, South Africa, and Zambia) Africa, which longitudinally assessed HIV acquisition (by ELISA) and BV (by Nugent score ≥7). We used previously generated CD101 sequence data for each case and control participant to create a binary variable indicating the presence/absence of any of 5 CD101 Ig-like variants.
resultsConfirming previously shown results in this cohort, Ig-like variants increased HIV-infection risk (adjusted hazard ratio [aHR], = 2.63; 95% confidence interval [CI], 1.41 to 4.89). BV was associated with 2.5-fold higher HIV-infection risk only in the absence of Ig-like variants (aHR = 2.47; 95% CI, 0.99 to 6.15; P = 0.052), whereas in the presence of Ig-like variants, BV was not associated with higher HIV-infection risk (aHR = 0.87; 95% CI, 0.35 to 2.15; P = 0.765); however, a test for interaction was nonsignificant (P = 0.116).
conclusionsWe hypothesized that both BV and CD101 Ig-like variants facilitate HIV acquisition by augmenting similar genital inflammation pathways. Our findings indicate that inflammatory mucosal effects of Ig-like variants may influence the impact of BV on HIV risk. Host-defined inflammatory pathways may be useful targets for HIV prevention.
