Hypertensive Disorders of Pregnancy and Primary Aldosteronism.
Article in medRxiv : the preprint server for health sciences, 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
Background: Hypertensive disorders of pregnancy (HDP) affect up to 15% of pregnancies and are linked to adverse maternal and fetal outcomes. Primary aldosteronism (PA) affects up to 25% of hypertensive patients. We examined PA prevalence in women with prior HDP and its relationship to hypertension trajectory. Methods: Adults from across the U.S.A. meeting guideline-recommended screening criteria for PA were prospectively tested. Women with a self-reported history of HDP completed a questionnaire examining the relationship between PA and hypertension trajectory. Results: Of 330 hypertensive parous women (62.4 ± 9.8y; 32.1% non-white), 83 (25.2%) reported a history of HDP. Women with HDP were younger at hypertension diagnosis (38.8 vs. 47.9y; p <0.001). The prevalence of a positive PA test was similarly high in those with and without HDP (26.5% vs 32%; Conclusion: Over 25% of women with hypertension and a prior pregnancy screened positive for PA, highlighting its high prevalence, irrespective of history of HDP. Women with HDP remain at elevated cardiovascular risk, and PA may represent a targetable contributor.
