The association between serum uric acid and homocysteine is mediated by metabolic risk factors.
Article in Scientific reports, 2025. 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
Previous studies have revealed a link between serum uric acid (SUA) and homocysteine (Hcy) levels, but it is unclear whether such relationship can be mediated by metabolic risk factors. This study evaluated the relationship between SUA and Hcy levels through a mediation analysis, examining the extent to which metabolic risk factors mediate this association. A total of 16,870 participants aged 20-60 years was consecutively enrolled at the Third Xiangya Hospital, Central South University. Data on health behaviours and medical history were collected through self-reported health questionnaires. Laboratory examinations were conducted by trained personnel via standardized methods. Logistic regression models were used to evaluate the associations between SUA and Hcy levels. Mediation analysis was conducted to explore the possible impact of metabolic risk factors on the SUA-Hcy relationship. There was a significant dose‒response relationship between higher SUA quartiles and increased hyperhomocysteinemia (HHcy) risk (P for trend < 0.01). Mediation analysis indicated that the relationship between SUA and HHcy was partially mediated by triglyceride (TG, 10.78%), diastolic blood pressure (DBP, 10.12%), systolic blood pressure (SBP, 7.63%), body mass index (BMI, 6.02%), and total cholesterol (TC, 0.56%); high-density lipoprotein cholesterol (HDL-C) negatively mediated this association, accounting for 13.03% of the effect. SUA is positively associated with HHcy risk and potentially mediated by metabolic factors such as HDL-C, TG, DBP, SBP, and BMI.
