Association Between Dietary Acid Load and Grip Strength in Adults 50 Years and Older: A Cross-Sectional Study.
Article in Calcified tissue international, 2024. 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
Minimal data exist on whether the acid-base balance of the diet is linked to muscle strength. The aim of this study was to determine if dietary acid load is associated with grip strength in a nationally representative sample of middle- to older-age adults. We examined the cross-sectional association of grip strength with dietary acid load quantified through potential renal acid load (PRAL) and net endogenous acid production (NEAP) in 4,059 adults aged 50 years and older in the 2011-2014 NHANES survey cycles. PRAL and NEAP were estimated from two 24-h recalls and categorized into sex-specific quartiles. Grip strength was measured on a dynamometer. Multiple linear regression models were used to determine the associations of PRAL and NEAP (as quartiles) with grip strength for men and women separately, adjusting for total energy, age, race/ethnicity, weight, physical activity, smoking, serum 25-hydroxyvitamin D, and estimated glomerular filtration rate. Mean grip strength was 26.8 ± 0.2 kg in women and 43.0 ± 0.4 kg in men. Adjusted grip strength was inversely associated with quartiles of PRAL (p
