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
Insulin resistance and impaired glucose metabolism are critical factors influencing female reproductive health. This study aimed to evaluate the association between estimated glucose disposal rate (eGDR), a surrogate marker of insulin resistance, and female infertility in the general population. We conducted a cross-sectional analysis of women aged 20 to 45 years from the National Health and Nutrition Examination Survey 2013 to 2020. Multivariable logistic regression, restricted cubic spline analysis, threshold analysis, and subgroup analyses were used to assess the association between eGDR and infertility. A total of 2430 women were included, and the prevalence of infertility was 14.9%. After adjustment for potential confounders, eGDR was negatively associated with the risk of female infertility (odds ratio [OR] = 0.80, 95% confidence interval [CI]: 0.70-0.92; P = .001). In tertile analyses, women in the highest eGDR tertile had a lower risk of infertility than those in the lowest tertile (OR = 0.51, 95% CI: 0.31-0.84; P = .009), with a significant trend across tertiles. Threshold analysis identified an inflection point at an eGDR value of 4.96. Subgroup analyses showed a significant interaction between eGDR and age. Higher eGDR was significantly associated with a lower risk of female infertility among U.S. women. These findings suggest that eGDR may be a useful marker for evaluating infertility risk related to insulin resistance.
