Association Between Sodium Density and Grip Strength Among Older Korean Adults: A Nationwide Cross-Sectional Study.
Article in Clinical interventions in aging, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeHandgrip strength is a key diagnostic criterion for sarcopenia, and sodium is an essential mineral for muscle contraction. We investigated the association between grip strength and sodium intake using sodium density. PATIENTS AND
methodsA total of 2982 older adults (aged ≥65 years) from the 2014-2016 Korea National Health and Nutrition Examination Survey were included. Dietary intake was assessed by a 24 hr dietary recall, and grip strength was measured using a digital grip strength dynamometer. Based on the recommendation of the Asian Working Group for Sarcopenia, low grip strength (dynapenia) was defined as <26 kg for men and <18 kg for women. Multivariable logistic regression was performed to estimate the adjusted odds ratio (OR) and 95% confidence interval (CI) and to investigate the association between the quartiles of sodium per calorie (mg/1000 kcal; sodium density) and dynapenia.
resultsA total of 577 subjects (19.3%) had dynapenia. Subjects in the second quartile of sodium density had the lowest prevalence of dynapenia and were defined as the reference group. Among women, those in the highest quartile of sodium density showed a significantly higher risk for dynapenia (OR 1.51, 95% CI 1.10-2.07). ORs in the first and third quartiles of sodium density were 1.01 (95% CI 0.74-1.38) and 1.18 (95% CI 0.89-1.58), respectively. However, there was no association between sodium density and dynapenia in men.
conclusionHigh sodium density was associated with dynapenia in older women. A balanced diet of minerals is important to preserve muscle strength among older adults.
