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

Ganoderma lingzhi is a traditional medicinal mushroom, and its extract contains many bioactive compounds. Triterpenoids and polysaccharides are the primary bioactive components that contribute to its medicinal properties. In this study, we quantified 18 triterpenoids, total triterpenoid content and total polysaccharide content in the ethanol and water extracts of G. lingzhi at different growth stages. Triterpenoids were quantified by liquid chromatograph-tandem mass spectrometry in the multiple-reaction-monitoring mode. Total triterpenoid and total polysaccharide content were determined by colorimetric analysis. The results indicated that the fruit bodies at an early growth stage had a higher content of ganoderic acid A, C2, I and LM2, as well as of ganoderenic acid C and D, than those at a later growth stage. In contrast, ganoderic acid K, TN and T-Q contents were higher in mature fruit bodies (maturation stage). The highest total triterpenoid and total polysaccharide contents were found in fruit bodies before maturity (stipe elongation stage or early stage of pileus formation). Our results provide information which will contribute to the establishment of an efficient cultivation system for G. lingzhi with a higher content of triterpenoids.
