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

Gamma interferon (IFN-gamma), a pleiotropic cytokine, is now known to be produced by macrophages as well as by NK cells, gammadelta cells, and activated T cells. The autocrine biological functions of IFN-gamma on the macrophage include the upregulation of major histocompatibility complex MHC class II and the activation to an antiviral state. In this study, the production of IFN-gamma by macrophages was demonstrated to correspond to antibacterial activity. Legionella pneumophila replicates intracellularly in thioglycolate (TG)-elicited macrophages (TG-macrophages) from A/J mice, while TG-macrophages from BALB/c mice restrict bacterial growth after an initial period of growth. BALB/c TG-macrophages were shown to express IFN-gamma mRNA at 24 and 28 h, which corresponded to the initiation of anti-L. pneumophila activity. Moreover, IFN-gammaneutralization by antibody treatment of the cultures resulted in increased L. pneumophila growth in the macrophages. In contrast, no IFN-gamma mRNA was expressed in TG-macrophages from A/J mice, where L. pneumophila grew unrestricted. As would be expected, IFN-gamma treatment decreased bacterial growth. An IFN-gamma-mediated antibacterial activity was, however, inducible in A/J macrophages by the addition of interleukin-12 following L. pneumophila infection. Thus, autocrine IFN-gamma is involved in anti-L. pneumophila activity associated with different growth patterns and appears to be important during intracellular infection.
