Causal relationship between serum uric acid levels and male infertility: a bidirectional two-sample Mendelian randomization study.

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
Background: Uric acid is the final metabolic product of purines in the human body and has been implicated in the pathogenesis of various diseases. Nevertheless, the relationship between serum uric acid levels and male infertility remains inconclusive. This Mendelian randomization (MR) study aims to elucidate the potential impact of serum uric acid levels on the risk of male infertility. Methods: We conducted the bidirectional MR analysis utilizing summary data from genome-wide association studies (GWAS) on serum uric acid levels and male infertility. The inverse variance weighted (IVW) method was employed to evaluate the primary outcomes, and multivariate MR analyses were conducted to combine estimates of the causal effects of multiple risk factors. Additionally, sensitivity analyses were performed to confirm the robustness of the results. Results: In the univariable MR analysis, serum uric acid levels did not exhibit a significant association with the risk of male infertility [IVW odds ratio (OR) 0.92, 95% confidence interval (CI): 0.614-1.390, P=0.70]. Similar conclusions were drawn from the reverse MR analysis (IVW OR 1.000, 95% CI: 0.997-1.003, P=0.96). In the multivariable MR (MVMR) analysis, after adjusting for confounding factors such as body mass index (BMI), type 2 diabetes, alcohol consumption, and smoking, serum uric acid levels remained unassociated with male infertility (IVW OR 0.839, 95% CI: 0.613-1.148, P=0.27). Consistent results were observed in the reverse analysis (IVW OR 1.003, 95% CI: 0.994-1.012, P=0.49). Conclusions: Our study provides genetic evidence indicating no significant causal relationship between serum uric acid levels and male infertility in the general population, suggesting that serum uric acid is not a potential risk factor for male infertility.
