Discordance and shortcomings of aldosterone suppression tests in primary aldosteronism.
Article in European journal of endocrinology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundThe saline suppression test (SST) and the captopril challenge test (CCT) have traditionally been used to confirm or exclude primary aldosteronism (PA). New guidelines recommend using these tests to predict the likelihood of unilateral PA. This study evaluated the diagnostic accuracy, consistency, and clinical implications of these tests.
methodsWe conducted a retrospective study of 531 patients with high-probability features of PA who underwent both SST and CCT to evaluate their accuracy and ability to predict unilateral PA. Adrenal lateralization and surgical treatment decisions were guided by individualized clinical judgment rather than strictly relying on SST/CCT results.
resultsThe rate of PA diagnosis ranged from 47.8% to 97.2% based on SST and CCT criteria. Discordance rates between SST and CCT ranged from 10.9% to 51.6%. In analyses restricted to only patients with clinically overt PA, where suppression testing is not considered necessary, the positivity rates of the SST and CCT were still suboptimal and test discordance persisted. Among patients with lateralizing PA, 6.6% to 27.9% had either a negative SST or CCT interpretation, and among those who achieved Primary Aldosteronism Surgical Outcome-defined biochemical cure after unilateral adrenalectomy, 4.1% to 39.8% had either a negative SST or CCT, and up to 5.1% had false-negative results on both tests.
conclusionsWell-established aldosterone suppression tests for PA demonstrated substantial inconsistency, false-negative interpretations, and the inability to reliably predict lateralization outcomes in PA. Aldosterone suppression testing, using SST and CCT, lack accuracy for the diagnosis and subtyping of PA in high-risk patients.
