Norisoboldine Induces Endothelium-Dependent Vasorelaxation and Attenuates Hypertension by Modulating Ca
Article in Antioxidants (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Vascular function is a direct factor affecting blood pressure, and it is a primary strategy for clinically controlling hypertension by regulating the constriction/relaxation of blood vessels. This study evaluates the vasodilatory and anti-hypertensive effects of norisoboldine (NOR), an isoquinoline alkaloid in Ayurvedic medicine. The rat thoracic aorta was isolated to investigate the vasodilatory effect, and L-NAME-induced hypertensive rats were established, respectively. In the isolated vascular ring, removal of the endothelium resulted in a significant decrease in the vasodilatory effect.
