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 attack and defense of infected cells and cytotoxic CD8 T cells occur in germinal centers in lymphoid tissue in chronic persistent HIV/SIV infection. Latently infected cells, the therapeutic target of HIV infection, accumulate in follicular helper T (Tfh) cells in lymphoid tissue; the impact of HIV-specific follicular CD8 (fCD8) T cells in lymphoid tissue on the latently infected cells remains unknown. We infected 15 cynomolgus macaques with SIVmac239 and examined the contribution of SIV-Gag-specific fCD8 T cells, defined by activation-induced markers (AIMs), to SIV-infected cells. Eight out of the 15 infected macaques served as progressors; a chronic phase combination antiretroviral therapy (cART) model was established for the eight macaques (progressors) with chronic persistent infection status, wherein cART was started in the chronic phase and discontinued after 27 weeks. Seven macaques that naturally controlled the viremia served as natural controllers. The frequency of SIV-Gag-specific fCD8 T cells was inversely correlated with the amount of cell-associated SIV-
