Racial and Ethnic Differences in Sodium Sources and Sodium Reduction Behaviors Among US Adults: NHANES 2017 to 2020 Prepandemic.
Article in Journal of the American Heart Association, 2025. 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
backgroundNearly all US adults exceed sodium recommendations, which increases cardiovascular risk. Understanding racial and ethnic differences in sodium sources and behaviors could lead to nuanced public health messaging, dietary interventions, and clinical guidance to achieve population-level sodium reduction more equitably. METHODS AND
resultsUsing National Health and Nutrition Examination Survey (NHANES) 2017 to 2020 prepandemic data, racial and ethnic differences in sodium sources and sodium-related behaviors (eg, salt use at the table and in food preparation, doctor advice to reduce sodium, attempts to reduce sodium, and label reading) were assessed using weighted chi-square. Given the nutrient database's assumption that rice is salted may be inappropriate for some ethnic groups, we conducted a secondary analysis altering this assumption. Pizza, soup, and chicken were top sources of sodium across racial and ethnic groups. For Asian American adults, 4 top sources were unique (eg, soy-based condiments). Black adults reported the highest rates of reducing sodium (67% versus 44% among White adults) and receiving physician sodium reduction advice (35% versus 18% among Asian American adults). Asian American adults were the most likely to frequently use salt during food preparation (66% versus Other Race adults 32%) but reported not using salt at the table (39% versus 18% among Mexican American adults). Assuming rice is unsalted reduces Asian American sodium intake estimates by ~325 mg/day.
conclusionsTo equitably address sodium intake, culturally appropriate advice on sources of sodium and salt usage may be needed, particularly for Asian American adults.
