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

backgroundMycobacterium tuberculosis is an unusual pathogen, persisting for years in infected persons despite an immune response. Erythropoietin-producing hepatoma (Eph) receptors are critical for tissue organization. One hallmark of tuberculosis is the presence of granulomas consisting of organized immune cells. The importance of granuloma structure makes it likely that Eph receptors play a role in immunity to tuberculosis.

methodsWe infected mice with low doses of M. tuberculosis by the aerosol method and examined the effects on ephA gene expression, pathology, composition of lymphocytes in the lungs (by flow cytometry), migration of CD4+ and CD8+ T cells, and numbers of cytokine-expressing cells.

resultsMice infected with M. tuberculosis displayed higher expression of ephA1 and ephA2 as well as ephrinA1, which encodes the ligand for EphA1 and EphA2. Interestingly, ephA2-/- mice displayed greater pathology, greater accumulation of T cells and dendritic cells, and higher levels of proinflammatory cytokines than did normal C57BL/6 mice. Furthermore, T cells from ephA2-/- mice migrated more efficiently than did those from C57BL/6 mice.

conclusionsThese observations suggest that ephA-related genes may provide a mechanism that M. tuberculosis uses to circumvent the host response, given that accumulation of T cells appears to be due to the inhibition of immune cell migration by EphA2. Ultimately, the absence of ephA2 results in greater clearance of M. tuberculosis during the chronic phase of infection, suggesting that induction of ephA2 is important for the survival of M. tuberculosis during latency.
