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

Many features of T-cell homeostasis in primates are still unclear, thus limiting our understanding of AIDS pathogenesis, in which T-cell homeostasis is lost. Here, we performed experiments of in vivo CD4(+) or CD8(+) lymphocyte depletion in 2 nonhuman primate species, rhesus macaques (RMs) and sooty mangabeys (SMs). Whereas RMs develop AIDS after infection with simian immunodeficiency virus (SIV), SIV-infected SMs are typically AIDS-resistant. We found that, in both species, most CD4(+) or CD8(+) T cells in blood and lymph nodes were depleted after treatment with their respective antibodies. These CD4(+) and CD8(+) lymphocyte depletions were followed by a largely lineage-specific CD4(+) and CD8(+) T-cell proliferation, involving mainly memory T cells, which correlated with interleukin-7 plasma levels. Interestingly, SMs showed a faster repopulation of naive CD4(+) T cells than RMs. In addition, in both species CD8(+) T-cell repopulation was faster than that of CD4(+) T cells, with CD8(+) T cells reconstituting a normal pool within 60 days and CD4(+) T cells remaining below baseline levels up to day 180 after depletion. While this study revealed subtle differences in CD4(+) T-cell repopulation in an AIDS-sensitive versus an AIDS-resistant species, such differences may have particular relevance in the presence of active SIV repli cation, where CD4(+) T-cell destruction is chronic.
