Association between uric acid to high-density lipoprotein cholesterol ratio (UHR) and female infertility: insights from a cross-sectional 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
backgroundInfertility in women of reproductive age is a major worldwide health problem. Oxidative stress, inflammatory responses, and dysregulation of lipid metabolism are among the factors that contribute to female infertility. The ratio of serum uric acid to high-density lipoprotein cholesterol (UHR), a novel composite biomarker that reflects oxidative stress and lipid metabolism, has not been extensively studied in relation to female infertility. This study aims to explore the associations between UHR levels and female infertility.
methodsThis cross-sectional study focused on females aged 18-44 years in the National Health and Nutrition Examination Survey from 2013 to 2018. The association between UHR and infertility was assessed by weighted multivariable logistic regression. Restricted cubic spline (RCS) analysis was employed to analyze the presence of nonlinear relationships between UHR and infertility. Stratified analyses were conducted to investigate the interactions between UHR and infertility in subgroups.
resultsOf the included 3087 women, 357 (11.56%) were recognized with infertility. When UHR was continuous, elevated UHR levels showed a positive association with infertility risk after comprehensive adjustment for confounding factors [odds ratio (OR) = 1.07, 95% confidence interval (CI): 1.02-1.12]. Compared with the lowest UHR level (UHR ≤ 6.14), women with the highest UHR level (UHR > 10.49) had higher odds of infertility (OR = 1.80, 95% CI: 1.03-3.14). A linear relationship was found between UHR and infertility in the RCS analysis. Stratified analyses did not discover any interactions between UHR and infertility in selected subgroups, including age group, educational level, body mass index category, marital status, diabetes, hypertension, hyperlipidemia, and menstrual cycle regularity (all p values for interaction were > 0.05).
conclusionsThe findings demonstrated significant linear associations between elevated UHR levels and increased odds of female infertility. UHR may serve as a potential biomarker for infertility that requires validation. Future studies should remedy the cross-sectional limitations of this study.
