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

backgroundInfection with the protozoan parasite Plasmodium is the cause of malaria. Plasmodium infects host erythrocytes causing the pathology of the disease. Plasmodium-infected erythrocytes can modulate the maturation of dendritic cells (DCs) and alter their capacity to activate T cells.

methodsMice infected with Plasmodium yoelii and isolated P. yoelii-infected erythrocytes were used to study their effect on the maturation of mouse dendritic cells.

resultsDCs are not able to mature in response to LPS injection during the late stage of P. yoelii infection in mice, indicating impaired functionality of these cells in vivo. P. yoelii- infected erythrocytes inhibit the maturation of DCs in vitro in a dose-dependent manner, which is consistent with the inhibition found during late infection when parasite burden is highest. The inhibition of DC maturation and the cytokine secretion profile of DCs are modulated by soluble factors released by P. yoelii-infected erythrocytes. A small, heat-stable, non-hydrophobic molecule of P. yoelii-infected erythrocytes rapidly inhibits the LPS induced phenotypic maturation of DCs in a reversible manner.

conclusionThese findings add evidence to the malaria associated immune suppression in vivo and in vitro and provide insight into the nature and mechanism of the Plasmodium factor(s) responsible for altering DC functions.
