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

Ten glycosidic compounds (1-10), including two novel amide glycosides and one new phenylpropanoid glycoside, were isolated from the fruits of Piper longum L. These novel compounds were identified as (E)-N-feruloylpiperidine 4'-O-β-d-glucopyranosyl-(1 → 4)-β-d-glucopyranoside (1), (E)-N-p-coumaroylpiperidine 4'-O-β-d-glucopyranosyl-(1 → 4)-β-d-glucopyranoside (2), and (E)-cinnamyl alcohol 9-O-β-d-glucopyranosyl-(1 → 4)-α-l-rhamnose-(1 → 6)-β-d-glucopyranoside (3) by detailed spectroscopic and spectrometric techniques. Acid hydrolysis was employed to determine the glycosidic linkages, facilitating the structural elucidation of these compounds. The anti-inflammatory activities of all isolated compounds were assessed, and the results demonstrated that compounds 8 and 9 exhibited moderate inhibitory effects on nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 cells.
