Dietary sodium, potassium, and cardiometabolic risk: A cross-sectional analysis of hypertension in U.S. adults from NHANES 2017-2018.
Article in PloS one, 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
backgroundThe relationships between dietary sodium and potassium intake and hypertension remain controversial, with recent population-based analyses yielding inconsistent findings. This study aimed to evaluate the associations of sodium and potassium intake with hypertension among U.S. adults and to explore potential interactions with demographic and lifestyle factors.
methodsWe conducted a cross-sectional analysis using data from 5,569 adults aged ≥20 years in the NHANES 2017-2018 cycle. Dietary intake was assessed using 24-hour dietary recall. Hypertension was defined based on self-reported diagnosis. Multivariable logistic regression models were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs). Restricted cubic spline models examined nonlinear trends, and subgroup analyses were stratified by sex, age, and BMI.
resultsNo significant associations were found between sodium or potassium intake and the odds of hypertension after adjusting for covariates (OR ≈ 1.00, P > 0.05) and findings were consistent when including the Na/K ratio. Results remained stable across sensitivity models and spline analysis. A non-significant inverse trend was observed for dietary fiber intake. Subgroup analyses suggested slightly stronger associations among older adults and individuals with obesity, although interaction terms were not statistically significant.
conclusionIn this nationally representative sample, sodium and potassium intake were not independently associated with hypertension risk. These findings highlight the complexity of diet-blood pressure relationships and the importance of considering broader dietary patterns and individual characteristics in hypertension prevention strategies.
