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

To investigate the role of glutathione (GSH) synthesis in the regulation on nuclear factor (NF)-kappaB activity and tumor necrosis factor-alpha (TNF-alpha) release by glutamine (GLN) in lipopolysaccharide (LPS)-stimulated alveolar type II (AT-II) epithelial cells of rat lungs. Primary cultured AT-II cells were pre-treated with various doses of GLN for 2, 8, 16, 24 h. At the 8 h time point before LPS stimulation, various doses of L: -buthionine-(S,R)-sulfoximine (BSO), an inhibitor of GSH synthesis, were added with 10 mM GLN. Then the cells were stimulated with 1 mug/ml LPS for 24 h. The cells were obtained for GSH measurement. TNF-alpha level in the supernatant was determined by enzyme-linked immunosorbent assay. NF-kappaB activity was assessed by electrophoretic mobility shift assay. Eight hours before LPS exposure was the best time point for GLN's enhancing GSH synthesis. LPS could significantly decrease the GSH level, increase NF-kappaB activation and TNF-alpha release in AT-II cells. Supplementation of GLN could increase the GSH level and attenuate the release of TNF-alpha in LPS-stimulated AT-II cells in a dose-dependant manner. And NF-kappaB activation also could be prevented by GLN. BSO could block the effect of GLN. As a precursor of GSH, glutamine could prevent the NF-kappaB activation and attenuate the release of TNF-alpha in LPS-stimulated AT-II cells and the effect may be mediated via GSH synthesis.
