Impact of Sodium on Blood Pressure and Well Being on Coastal Population: A Social Pharmacy Perspective.
Article in Cureus, 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
Background Coastal communities often exhibit dietary habits characterized by high sodium intake due to the frequent consumption of salted and preserved foods. Such patterns may contribute to elevated blood pressure and impaired well-being. This study examined the relationship between sodium intake, blood pressure, and health-related quality of life among fishermen living on Madura Island, Indonesia. Methods A cross-sectional study was conducted from December 2023 to November 2024 involving 137 adult fishermen who met the inclusion criteria and provided informed consent. Sodium intake was assessed using a coastal-adapted Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ) and quantified using the Indonesian Food Composition Table (TKPI). Blood pressure was measured following standardized procedures using a digital sphygmomanometer. Quality of life was evaluated using the EQ-5D-5L instrument. Spearman correlation tests were used to determine associations between sodium intake, blood pressure, and quality of life. Results Most respondents consumed sodium above recommended levels, with 75.18% exhibiting high intake (>1500 mg/day). More than half (54.74%) were categorized as Stage 1 hypertension, and only 32.85% showed normal blood pressure. Quality of life scores indicated mild to moderate limitations, predominantly in the pain/discomfort and usual activities domains. A modest but significant correlation was observed between sodium intake and blood pressure (r = 0.192, p = 0.047), while no meaningful association was found between sodium intake and quality of life (r = -0.015, p = 0.877). Conclusion High sodium consumption among Madura fishermen is associated with elevated blood pressure, despite generally preserved quality of life. Routine screening, community-based nutrition education, and targeted interventions promoting reduced-sodium dietary practices are recommended to prevent undiagnosed hypertension and improve long-term health outcomes in coastal populations.
