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

Two new canthin-6-one alkaloids, 4,9-dimethoxy-5-hydroxycanthin-6-one (1) and 9-methoxy-(R/S)-5-(1-hydroxyethyl)-canthin-6-one (2), together with fifteen known ones were isolated from the roots of Thailand Eurycoma longifolia Jack. Among the known canthin-6-one alkaloids, compounds 9 and 16 were isolated from the Eurycoma genus for the first time. Meanwhile, the nitric oxide (NO) inhibitory activities of all isolates were examined in lipopolysaccharide (LPS)-stimulated RAW264.7 cells at 50 µM. Moreover, a dose-dependent experiment was conducted for active compounds 1, 2, 4, 6, 7, 10, 12-17 at the concentration of 10, 25, and 50 µM, respectively. Consequently, compounds 1, 4, 6, 7, 12, 14, 15, as well as 17 were found to inhibit NO release from RAW264.7 cells in a dose-dependent manner. Two new canthin-6-one alkaloids, 4,9-dimethoxy-5-hydroxycanthin-6-one (1) and 9-methoxy-(R/S)-5-(1-hydroxyethyl)-canthin-6-one (2), together with fifteen known ones were isolated from the roots of Thailand Eurycoma longifolia Jack. Among them, 1, 4, 6, 7, 12, 14, 15, as well as 17 were found to inhibit NO release from RAW264.7 cells in a dose-dependent manner at the concentration of 10, 25, and 50 µM.
