Association of Dietary Potassium Intake With Abdominal Aortic Calcification and Pulse Pressure in US Adults.
Article in Journal of renal nutrition : the official journal of the Council on Renal Nutrition of the National Kidney Foundation, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectivesArterial calcification contributes to cardiovascular mortality. Based on a recent animal study, we hypothesized that higher dietary potassium intake was associated with less abdominal aortic calcification (AAC) and lower arterial stiffness among adults in the United States.
methodsCross-sectional analyses were performed on participants over 40 years old from the National Health and Nutrition Examination Survey 2013-2014. Dietary potassium intake was categorized into quartiles (Q1: <1911, Q2: 1911-2461, Q3: 2462-3119, and Q4: >3119 mg/d). Primary outcome AAC was quantified using the Kauppila scoring system. AAC scores were categorized into no AAC (AAC = 0, reference group), mild/moderate (AAC >0 to ≤ 6), and severe AAC (AAC >6). Pulse pressure was used as a surrogate for arterial stiffness and examined as a secondary outcome.
resultsAmong 2,418 participants, there was not a linear association between dietary potassium intake and AAC. Higher dietary potassium intake was associated with less severe AAC when comparing dietary potassium intake in Q2 with Q1 (odds ratio 0.55; 95% confidence interval: 0.34 to 0.92; P = .03). Higher dietary potassium intake was significantly associated with lower pulse pressure (P = .007): per 1000 mg/d higher dietary potassium intake, pulse pressure was 1.47 mmHg lower in the fully adjusted model. Compared to participants with dietary potassium intake in Q1, pulse pressure was 2.84 mmHg lower in Q4 (P = .04).
conclusionsWe did not find a linear association between dietary potassium intake and AAC. Dietary potassium intake was negatively associated with pulse pressure.
