Sex-based disparities in the association between uric acid levels and anxiety: a cross-sectional analysis of nationwide data in Korea.

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
backgroundUric acid has antioxidant properties, and several studies have suggested its neuroprotective effects. Despite reports of increased oxidative damage and decreased antioxidants in anxiety disorders, findings remain inconclusive. This study investigated the association between serum uric acid levels and anxiety symptoms, stratified by sex, using nationwide data from South Korea.
methodsData were derived from the Korea National Health and Nutrition Examination Survey, which included 2,228 males and 2,805 females. Presence of anxiety symptoms was defined as a Generalized Anxiety Disorder 7-item scale (GAD-7) score of ≥ 10. Study participants were categorized into three groups based on serum uric acid levels: 1 (lowest) to 3 (highest). Multivariable logistic regression analyzed the association between uric acid levels and anxiety symptoms, stratified by sex.
resultsCompared to reference group 2, females in group 1 had increased anxiety symptoms (odds ratio (OR) 2.28, 95% confidence interval (CI) 1.48-3.49). When anxiety symptoms were defined as a GAD-7 score of ≥ 5, females in groups 1 (OR 1.68, 95% CI 1.30-2.16) and 3 (OR 1.35, 95% CI 1.04-1.74) both showed more anxiety symptoms than group 2, with a U-shaped relationship between uric acid levels and anxiety symptoms. In males, uric acid levels weren't significantly linked to anxiety symptoms.
conclusionsThis study indicates that low serum uric acid levels are associated with a higher prevalence of anxiety symptoms only in females, suggesting involvement of oxidative stress in anxiety disorders and its sex-based variation.
