Article in Pharmacology research & perspectives, 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
As living standards improve and the population ages, cardiovascular disease poses a significant threat to human health. Apigenin, a flavonoid compound found in many fruits and vegetables native to warm climates, is named after celery because it is found in the highest concentrations in this plant. Apigenin exhibits various physiological and pharmacological activities. However, its protective effects on the cardiovascular system and the underlying mechanisms are unclear. The aim of this study is to investigate the role of apigenin and its mechanism in protecting against myocardial cell damage induced by OGD/R in H9c2 rat myocardial cells. MTT experiments demonstrated that apigenin protects cells from OGD/R-induced damage under OGD/R conditions. Molecular mechanism studies showed that apigenin (API) inhibits HIF-1α protein expression and promotes miR-20a expression under OGD/R conditions. This reduces the expression of autophagy-related proteins, inhibits cellular autophagy, and SOD activity. Thus, API exerts a protective effect on cells under OGD/R conditions. These results suggest that apigenin protects cells from oxidative stress damage by inhibiting HIF-1α expression and promoting miR-20a expression, thereby reducing autophagy levels in H9c2 cells under OGD/R conditions.
