Effect of a Salt Reduction Campaign in a Community Clinic: A Retrospective Study.
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
backgroundExcessive sodium chloride (salt) intake is a risk factor for noncommunicable diseases, such as hypertension, and initiatives to reduce salt intake are essential. This study assessed whether a salt reduction campaign reduced salt intake in outpatients attending a community clinic.
methodsOf 2,429 outpatients whose baseline estimated salt intake was measured using spot urine during the campaign conducted from February 1 to June 30, 2018, 655 outpatients (42.4% female, mean age of 61.6 ± 13.1 years) with a baseline salt intake of ≥10 g/day and ≥2 salt intake measurements within six months of the campaign were included. During the campaign, healthcare providers displayed information on low-salt foods and a poster depicting the association between excess salt intake and hypertension, and encouraged outpatients to measure their salt intake. The primary outcome was the change in salt intake.
resultsSalt intake decreased from 11.6 ± 1.69 to 9.4 ± 2.44 g/day (p < 0.001), body mass index (BMI) decreased from 27.4 ± 5.0 to 27.2 ± 5.0 kg/m² (p < 0.001), and systolic blood pressure (SBP) decreased from 132.3 ± 13.0 to 131.1 ± 13.5 mmHg (p = 0.028) in this population. Correlation analysis of the factors associated with changes in salt intake identified changes in BMI (r = 0.192, p < 0.001) and SBP (r = 0.176, p < 0.001). Estimated glomerular filtration rate decreased slightly; however, no clinically significant renal events were identified.
conclusionThis simple campaign represents a practical strategy to reduce salt intake in routine clinical practice.
