Endothelium-independent vasodilator effect of isocorynoxeine in vitro isolated from the hook of Uncaria rhynchophylla (Miquel).
Article in Naunyn-Schmiedeberg's archives of pharmacology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
This study was designed to investigate the vasorelaxant effects and underlying mechanism of isocorynoxeine (ICN), one of the indole alkaloids from Uncaria hooks, on isolated mesenteric arteries in vitro. The myograph system was applied for isometric tension recording in the vascular rings. ICN relaxed both endothelium-intact and endothelium-denuded rat vascular rings precontracted with phenylephrine or KCl in a dose-dependent manner. Propranolol, tetraethylammonium, BaCl
