Segmental Adrenal Venous Sampling in Unilateral Primary Aldosteronism With Apparent Bilateral Aldosterone Suppression.
Article in JCEM case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Apparent bilateral adrenal suppression (ABAS), where aldosterone/cortisol ratios in both adrenal veins are lower than in the inferior vena cava, yields uninterpretable adrenal venous sampling (AVS) results and is poorly understood. A 57-year-old male with hypertension and spontaneous hypokalemia was admitted to our hospital. Confirmatory tests established a diagnosis of primary aldosteronism (PA). Initial AVS indicated ABAS, but unilateral PA remained possible due to elevated aldosterone, low renin, hypokalemia, and a right adrenal nodule (8 × 7 mm) on computed tomography. Subsequently, a second, super-selective AVS identified tributaries from areas of aldosterone hypersecretion, enabling accurate localization of unilateral PA. ABAS may occur due to anatomical factors such as dilution by tributaries from nonaldosterone-producing adenoma (APA) areas with suppressed aldosterone production. Super-selective AVS proves beneficial in diagnosing unilateral PA concealed within ABAS by pinpointing tributaries from APA regions.
