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

Free radicals play an important role in the initiation and progression of inflammatory bowel disease (IBD). Therefore, the reduction or elimination of adverse oxidant effects can provide novel therapy for IBD. Here, the antioxidant capacity and protective effects of a new class of chemically modified hetastarch (polynitroxyl starch, or PNS) plus 4-hydroxyl-2,2,6,6-tetramethylpiperidine-N-oxyl (Tempol or TPL) (PNS/TPL) were assessed in a model of colitis. The superoxide scavenging capacity of PNS/TPL-that is, the inhibition of the reduction of cytochrome c in the presence of xanthine/xanthine oxidase (X/XO)-was evaluated in vitro. The effects of PNS/TPL on X/XO-induced neutrophil endothelial adhesion in vitro were investigated. Also, this study tested the protection produced by PNS/TPL in a mouse model of trinitrobenzene sulfonic acid (TNBS)-induced colitis. PNS/TPL was given intravenously immediately before (< 30 min) and intraperitoneally at 24 and 72 hr after TNBS induction. The body weight and survival rate of the mice were checked daily. Colonic mucosal damage was assessed on the 7th day by measuring intestinal permeability to Evans blue (EB) in vivo. The ability of PNS to reoxidize bioreduced TPL was documented by whole-body electron paramagnetic resonance (EPR) detection. We found that PNS or TPL exhibits superoxide dismutase (SOD)-like activity, with approximately 2% of SOD activity occurring on a molar basis. The endothelial-neutrophil adherence induced by X/XO was significantly inhibited by PNS/TPL but not by TPL alone. PNS/TPL protected against cachexia and mortality, both usually induced by TNBS. Epithelial permeability was increased significantly in TNBS mice but was ameliorated by the administration of PNS/TPL. In conclusion, PNS/TPL may be beneficial in the treatment or prevention of IBD through its antioxidant effects, which inhibit oxidant-mediated leukocyte adhesion and injury to endothelial cells.
