Corticosterone binds α
Article in Hypertension research : official journal of the Japanese Society of Hypertension, 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
Glucocorticoids are classically associated with hypertension, but their acute vascular effects remain incompletely understood. Female rats were selected due to their higher basal and stress-induced corticosterone levels, making them a physiologically relevant model. We investigated whether corticosterone directly modulates α1-adrenoceptor-mediated vasoconstriction in a strain- and age-dependent manner in female spontaneously hypertensive (SHR) and normotensive Wistar Kyoto (WKY) rats. Vascular reactivity was evaluated in pithed rats and isolated aortic rings from SHR and WKY rats across different ages (young, aged, senescent). Concentration-response curves to phenylephrine were performed under control conditions, after acute corticosterone, and in the presence of selective α
