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

The acute phases of human immunodeficiency virus (HIV) and simian immunodeficiency virus (SIV) infection are characterized by rapid and profound depletion of CD4+ T cells from the guts of infected individuals. The large number of CD4+ T cells in the gut (a large fraction of which are activated and express the HIV/SIV coreceptor CCR5), the high level of infection of these cells, and the temporal coincidence of this CD4+ T-cell depletion with the peak of virus in plasma in acute infection suggest that the intestinal mucosa may be the major source of virus driving the peak viral load. Here, we used data on CD4+ T-cell proportions in the lamina propria of the rectums of SIV-infected rhesus macaques (which progress to AIDS) and sooty mangabeys (which do not progress) to show that in both species, the depletion of CD4+ T cells from this mucosal site and its maximum loss rate are often observed several days before the peak in viral load, with few CD4+ T cells remaining in the rectum by the time of peak viral load. In contrast, the maximum loss rate of CD4+ T cells from bronchoalveolar lavage specimens and lymph nodes coincides with the peak in virus. Analysis of the kinetics of depletion suggests that, in both rhesus macaques and sooty mangabeys, CD4+ T cells in the intestinal mucosa are a highly susceptible population for infection but not a major source of plasma virus in acute SIV infection.
