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
objectiveSerum uric acid (SUA), a non-protein antioxidant, exerts anti-inflammatory and antioxidative stress effects. This study aimed to investigate the association between SUA levels and the risk of benign prostatic hyperplasia (BPH).
methodsThis cross-sectional study included 48 653 adult men who underwent health checkups at the Health Examination Center of the Affiliated Hospital of Yangzhou University in 2022. Data on demographics, clinical history and laboratory parameters were collected. Multivariable logistic regression models were used to analyse the relationship between SUA levels and BPH risk, with further exploration in different subgroups.
resultsLogistic regression analysis revealed a significantly decreased risk of BPH among participants in the highest SUA quartile (Q4) compared with those in the lowest quartile (Q1) (fully adjusted OR=0.83, 95% CI: 0.78 to 0.90, p<0.0001). Subgroup analyses demonstrated that this inverse association was more pronounced in subgroups of age>60 years (Q4: OR=0.77, 95% CI: 0.68 to 0.87, p<0.0001), non-obesity (Q4: OR=0.81, 95% CI: 0.75 to 0.87, p<0.0001), without non-alcoholic fatty liver disease (NAFLD) (Q4: OR=0.81, 95% CI: 0.73 to 0.89, p<0.0001), hypertension (Q4: OR=0.81, 95% CI: 0.74 to 0.89, p<0.0001) and without diabetes (Q4: OR=0.84, 95% CI: 0.78 to 0.90, p<0.0001). Curve fitting revealed that higher SUA levels were associated with a lower risk of BPH even in the presence of increased BPH risk factors such as diabetes and hypertension.
conclusionsThis study demonstrates a significant inverse association between SUA levels and BPH risk, particularly in subgroups of older age, non-obesity, absence of NAFLD, hypertension and absence of diabetes. This suggests a potential protective role of SUA in BPH development, highlighting the potential value of maintaining SUA levels within a reasonable range for BPH prevention.
