Evaluation of Predictive Risk Factors of Persistent Hypertension in Hyperaldosteronism After Surgery.

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: Primary hyperaldosteronism (PHA) is a common cause of secondary arterial hypertension (AH), characterized by autonomous aldosterone secretion. It is frequently underdiagnosed and may persist even after surgical intervention. Objectives: The present study aimed to identify preoperative factors that could predict whether hypertension would persist or normalize following surgery and to outline relevant diagnostic characteristics. Methods: We conducted a descriptive, analytic, retrospective cohort study at a single center. The study included patients with PHA who were followed up at the Department of Endocrinology, Diabetology, and Nutrition in a hospital affiliated with Mohamed the First University of Oujda (CERBO), admitted between December 2014 and August 2023. Data were retrospectively collected from patient records over a 9-year period, involving 27 patients with PHA confirmed by an elevated aldosterone-to-renin ratio (ARR). Persistent disease was defined by persistent hypokalemia and hypertension (blood pressure > 140/90 mm Hg) after six months. Patients were divided into two groups: Those with complete resolution of hypertension (group A) and those with persistent hypertension (group B). Data were analyzed using SPSS version 21. Results: The mean age of patients was 48.47 ± 10.87 years, with a female predominance (66.7%). The etiological assessment identified Conn's adenoma in 70.4% (n = 19) of cases and bilateral adrenal hyperplasia in 29.6% (n = 8). Surgery was performed in 51.9% (n = 14) of cases, with 50% (n = 7) maintaining persistent hypertension post-surgery, while 28.6% (n = 4) showed a reduction in antihypertensive medications. Two predictive factors for persistent hypertension were identified: Age > 50 years and hypertension duration > 5 years. Predictive factors for normalization of hypertension post-surgery included systolic blood pressure (SBP) < 140 mm Hg, diastolic blood pressure (DBP) < 90 mm Hg, glomerular filtration rate (GFR) > 90 mL/min/1.75 m Conclusions: This study demonstrates that PHA can lead to resistant hypertension, highlighting the necessity for further research in this area.
