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

background

objectiveThe objective of the study was to isolate the active compound from the methanolic extract of

methodsExtraction was done using continuous extraction with methanol as a solvent. The extract was then fractionated using liquid-liquid extraction, vacuum liquid chromatography, and radial chromatography. Recrystallization was done for purification. The structure of the compound was determined by Ultraviolet-Visible and (1D and 2D) nuclear magnetic resonance (NMR) spectrometer.

resultsThe isolate showed maximum wavelengths at 347 (band I) and 296 (band II) nm. After addition of NaOH and CH

conclusionDemethoxymatteucinol was isolated for the first time from SUMMARY: One flavonoid compound, which 5,7-dihydroxy 6,8-dimethyl flavanone (demethoxymatteucinol), was isolated from the methanol extract of
