Practical recommendations for antihypertensive therapy during the primary aldosteronism screening test.
Article in Endocrine, 2024. 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
backgroundThe aldosterone-to-renin activity ratio (ARR) is recommended as a screening test for primary aldosteronism (PA). The use of antihypertensive medication is one of the most important factors to take into account when interpreting the ARR.
objectivesThe goal of this study was to compare the effect of various antihypertensive drug classes on biochemical testing and provide practical recommendations for antihypertensive medication regimens in patients suspected of having PA.
methodsWe retrospectively investigated 4218 hypertensive patients who underwent PA detection between January 2020 and February 2023. Finally, 25 patients with essential hypertension (EH) and 39 with PA were involved. The enrolled EH patients were selected from EH patients with at least two screening tests with interfering medication changes for at least 4 weeks.
resultsA total of 2/18 (11.1%) EH patients had opposite screening results after angiotensin II receptor blockers (ARBs), angiotensin-converting enzyme inhibitors (ACEIs), dihydropyridine-calcium channel blockers (DHP-CCBs) and diuretics were withdrawn. A total of 3/3 (100%) of the patients were initially screened as positive but had results that tested negative after β-blockers withdrawal. A total of 3/39 (7.7%) PA patients were misdiagnosed with EH with drug effects. Only plasma renin activity was markedly reduced after antihypertensive medication washout (P = 0.0173).
conclusionsNot every patient receiving β-blockers, ACEIs, ARBs and DHP-CCBs with negative reports needed withdrawal or switching antihypertensive drugs. We recommend that patients be left on a regimen that includes β-blockers, ACEIs, ARBs, DHP-CCBs and spironolactone when determining the ARR during the initial test.
