Broad and potent neutralizing antibody responses elicited in natural HIV-2 infection.
Article in Journal of virology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 40 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
Compared with human immunodeficiency virus type 1 (HIV-1), little is known about the susceptibility of HIV-2 to antibody neutralization. We characterized the potency and breadth of neutralizing antibody (NAb) responses in 64 subjects chronically infected with HIV-2 against three primary HIV-2 strains: HIV-2(7312A), HIV-2(ST), and HIV-2(UC1). Surprisingly, we observed in a single-cycle JC53bl-13/TZM-bl virus entry assay median reciprocal 50% inhibitory concentration (IC(50)) NAb titers of 1.7 × 10(5), 2.8 × 10(4), and 3.3 × 10(4), respectively. A subset of 5 patient plasma samples tested against a larger panel of 17 HIV-2 strains where the extracellular gp160 domain was substituted into the HIV-2(7312A) proviral backbone showed potent neutralization of all but 4 viruses. The specificity of antibody neutralization was confirmed using IgG purified from patient plasma, HIV-2 Envs cloned by single-genome amplification, viruses grown in human CD4(+) T cells and tested for neutralization sensitivity on human CD4(+) T target cells, and, as negative controls, env-minus viruses pseudotyped with HIV-1, vesicular stomatitis virus, or murine leukemia virus Env glycoproteins. Human monoclonal antibodies (MAbs) specific for HIV-2 V3 (6.10F), V4 (1.7A), CD4 binding site (CD4bs; 6.10B), CD4 induced (CD4i; 1.4H), and membrane-proximal external region (MPER; 4E10) epitopes potently neutralized the majority of 32 HIV-2 strains bearing Envs from 13 subjects. Patient antibodies competed with V3, V4, and CD4bs MAbs for binding to monomeric HIV-2 gp120 at titers that correlated significantly with NAb titers. HIV-2 MPER antibodies did not contribute to neutralization breadth or potency. These findings indicate that HIV-2 Env is highly immunogenic in natural infection, that high-titer broadly neutralizing antibodies are commonly elicited, and that unlike HIV-1, native HIV-2 Env trimers expose multiple broadly cross-reactive epitopes readily accessible to NAbs.
