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

Antioxidant enzymes are thought to be important for the survival of pathogenic Neisseria species. We have further characterized the glutathione peroxidase homolog gene (gpxA), which we recently isolated from Neisseria meningitidis FAM20 (T.D.E. Moore and P.F. Sparling, Infect. Immun. 63:1603-1607, 1995). GpxA was found to be produced constitutively in vivo. An isogenic, omega insertion mutant in the gpxA gene was constructed and characterized. The gpxA insertion mutant was much more sensitive to the oxidative stress caused by paraquat and slightly more sensitive to hydrogen peroxide. This is the first demonstration of a phenotype arising from a mutation of a glutathione peroxidase homolog gene in a prokaryotic organism. Protection of the cell by GpxA from the effects of oxidative stress caused by aerobic metabolism may contribute to the ability of Neisseria meningitidis to cause disease in the human host.
