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

Harpagophytum procumbens, popularly known as devil's claw, is a plant commonly used in the treatment of diseases of inflammatory origin. The anti-inflammatory effects of H. procumbens have been studied; however, the mechanism of action is not elucidated. It is known that excess of reactive oxygen and nitrogen species may contribute to increasing tissue damage due to inflammation. In the present study, we examined the effects of H. procumbens infusion, crude extract and fractions on lipid peroxidation (brain homogenates) induced by different pro-oxidants (Fe(2+) or sodium nitroprusside) and the effects of ethyl acetate fraction (rich in phenolic compounds) on antioxidant defenses (catalase activity and thiol levels) and cell damage (brain cortical slices) induced by different pro-oxidants. All tested extracts of H. procumbens inhibited lipid peroxidation in a concentration-dependent manner. Furthermore, the ethyl acetate fraction had the highest antioxidant effects either by decreasing lipid peroxidation and cellular damage or restoring thiols levels and catalase activity. Taken together, our results showed that H. procumbens acts either by preventing oxidative stress or loss of cell viability. Thus, the previously reported anti-inflammatory effect of H. procumbens could also be attributed to its antioxidant activity.
