Sodium, potassium, and calories: implications for implementing a recommended diet in adults with hypertension.
Article in American journal of hypertension, 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
backgroundAchieving evidence-based dietary recommendations for sodium and potassium are key lifestyle modifications for adults with hypertension. This study aimed to investigate how dietary recommendations have been followed in US adults with hypertension over time.
methodsCross-sectional data on adults with hypertension was pooled from 12 National Health and Nutrition Examination Surveys (1999-2023). Dietary electrolyte intake was stratified as: (1) sodium ≤2300 mg/day (recommended) or ≤1500 mg/day (ideal), and (2) potassium ≥3500 mg/day (recommended) or ≥4700 mg/day (ideal).
resultsFrom 1999 to 2023, 29.4% (95% confidence interval: 28.6-30.1) and 20.3% (19.6-21.0) of adults with hypertension met recommended sodium and potassium intakes, respectively, with 1.3% (1.1-1.5) meeting both levels. Adults with hypertension meeting ideal intakes for sodium, potassium, and both represented 9.5% (9.1-10.0), 6.1% (5.7-6.6), and 0.03% (0.01-0.06), respectively. The proportion meeting recommended thresholds for sodium has followed a U-shape over time reaching a minimum [24.3% (21.6-26.9)] in 2011-12 before increasing to 34.5% (31.3-37.7) in 2021-23 (P < .001). The proportion meeting the recommended potassium intake, however, has declined over time [yearly prevalence ratio = 0.99 (0.98-0.99), P < .001] reaching the lowest point [15.3% (13.5-17.0)] in 2021-23. The correlations between intakes of sodium and potassium, calories and sodium, and calories and potassium were 0.62, 0.77, and 0.71, respectively.
conclusionsA low percentage of adults with hypertension met both recommended sodium and potassium intakes with higher intakes of potassium associated with high sodium and calories.
