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

backgroundAgaricus brasiliensis (A. brasiliensis) is a medicinal mushroom that exerts various pharmacological actions. We previously demonstrated that different cultivation conditions altered the activity of the polyphenol-related enzymes from this mushroom. However, the influence of cultivation conditions on the antioxidant activity of the fruiting bodies remains unclear. Therefore, in this study we compared the antioxidative effects of fruiting bodies of A. brasiliensis cultivated outdoors and indoors. In addition, we assessed whether different cultivation methods affected the hepatoprotective effects against CCl4-induced liver injury.

methodsWe assessed the antioxidative effects of mushrooms cultivated in open-air or indoors using the DPPH radical-scavenging assay. Furthermore, we prepared experimental feeds containing outdoor- or indoor-cultivated A. brasiliensis. Acute liver injury was induced by CCl4 injection in mice that consumed feed containing outdoor- or indoor-cultivated A. brasiliensis. The hepatoprotective effects of these mushrooms were then evaluated by monitoring the reduction in the circulating levels of alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase. The significance of the differences between the means was assessed using Student's t-test. Finally, histopathological analysis of liver was performed.

resultsIn the DPPH assay, the antioxidant activity of outdoor-cultivated A. brasiliensis was higher than that of indoor-cultivated mushroom. Moreover, in the mouse model of CCl4-induced hepatitis, the oral administration of outdoor-cultivated A. brasiliensis reduced liver damage significantly, but indoor-cultivated mushrooms failed to inhibit hepatitis. The hepatoprotective effects of outdoor-cultivated A. brasiliensis were observed even when ingestion commenced only 1 day before CCl4 injection, and these effects were not affected by excessive heat treatment.

conclusionsOutdoor cultivation significantly enhanced the antioxidative activity of A. brasiliensis fruiting bodies. In addition, outdoor-cultivated A. brasiliensis was more effective at protecting against CCl4-induced liver injury in mice than mushrooms grown in a greenhouse.
