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.
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 murine Nramp1 (natural-resistance-associated macrophage protein) locus confers innate resistance against intracellular macrophage pathogens. The gene encodes a transporter molecule, which is rapidly recruited to the phagosome. Nramp1 functions as an iron transporter by transporting iron into the phagosome. Within the phagosome iron mediates anti-microbial killing by hydroxyl radical formation through the iron-catalysed Fenton/Haber-Weiss reaction. In addition to its effects on the growth of intracellular pathogens, Nramp1 exerts a wide range of pleiotropic effects in activated macrophages. One of these pleiotropic effects is the increased stability of a variety of mRNA species, including Nramp1 mRNA. In the present study, the stability of Nramp1 mRNA in Mycobacterium avium infected RAW264. 7 macrophages expressing either the Nramp1(Gly169) resistant allele or the Nramp1(Asp169) susceptible allele was examined. Nramp1 mRNA stability was greater in Nramp1(Gly169) macrophages than in Nramp1(Asp169) macrophages. The increase in Nramp1 mRNA stability in resistant macrophages was inhibited by antioxidants and protein kinase C (PKC) inhibitors, suggesting that Nramp1 mRNA stability is regulated by an oxidant-generated signalling pathway that requires PKC activity. This was corroborated by treating Nramp1(Asp169) macrophages with menadione, which generates reactive oxygen species within cells. Menadione increased Nramp1 mRNA stability to the level observed in resistant macrophages; this increase was also inhibited by a PKC inhibitor. Further, PKC activity was found to be greater in M. avium-infected Nramp1(Gly169) macrophages than in infected Nramp1(Asp169) macrophages and inhibited by treatment with an antioxidant.
