1 · What the graph read from it

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.

2 · The registry

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

CD4(+) T cell dysfunction in HIV-1 infection is associated with increased CTLA-4 and TGF-beta expression. In this study we described a population of TGF-beta-positive CD4(+) T cells with multiple HIV specificities. These HIV-specific TGF-beta-positive CD4(+) T cells did not display the immunophenotypic patterns traditionally attributed to regulatory CD4(+) T cells. TGF-beta-positive CD4(+) T cells were FOXP3 negative, CD25 negative, and displayed a heterogeneous surface expression of CD127. We also examined one potential mechanism for regulating TGF-beta expression by HIV-specific CD4(+) T cells. Blocking of the TGF-beta receptor II led to increased HIV-specific IFN-gamma-positive CD4(+) and CD8(+) T cell responses. Interestingly, HIV-specific TGF-beta-positive CD4(+) T cells did not substantially express CTLA-4. Nevertheless, CTLA-4 blockade resulted in a significant decrease in HIV-specific TGF-beta-positive CD4(+) T cell responses, and a concomitant increase in HIV-specific IFN-gamma-positive CD4(+) T cell responses. Our study proposes a mechanism by which HIV-specific TGF-beta production may be regulated by CTLA-4 engagement.
