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

The present study was designed to explore the flavonoid contents and the radical scavenging activities of 50% ethanol extracts of leaves, stems, rachis and roots of Dryopteris erythrosora. The total flavonoid contents in various parts were determined as: stems > roots > rachis > leaves. All extracts from different parts of D. erythrosora showed strong bioactivities. The DPPH free radical scavenging abilities of extracts were determined as: stems > root > rachis >> leaves. This trend is reciprocal proportion to the total flavonoid contents in leaves, stems, rachis and roots of D. erythrosora extracts. The superoxide anion scavenging abilities of ethanol extracts were determined as: stems > leaves > rachis > root. It illustrated that there are strong superoxide anion scavengers in D. erythrosora. It is worth to separate and identify these components in future.
