Serum creatinine as a risk factor for endometriosis: insights from cross-sectional study, mendelian randomization analysis, and diagnostic model 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
backgroundEndometriosis (EM) is a prevalent gynecological condition impacting roughly 10% of women of reproductive age worldwide, causing chronic pain, infertility, and menstrual irregularities. Traditional diagnosis typically relies on invasive surgical methods, and non-invasive diagnostic techniques remain underdeveloped. This study seeks to investigate the association between creatinine levels and endometriosis through cross-sectional analysis and mendelian randomization (MR) analysis, while also developing and assessing diagnostic models.
methodThis research integrates data from the NHANES database (1999-2006) and the affiliated hospital of Jining Medical College in China. The study cohort consists of women aged 20-60, with data collection covering age, race, education level, marital status, family income, weight, height, body mass index(BMI), and serum creatinine levels. Logistic regression models were used for univariate and multivariate analyses. Bidirectional MR analysis, utilizing genetic variation data from Large Genome Association Studies (GWAS), was performed to evaluate causal relationships using the inverse variance weighted (IVW) method, complemented by sensitivity analysis. A diagnostic model based on data from top-tier hospitals in China was constructed and its performance assessed through receiver operating characteristic(ROC) curves, area under the curve(AUC) values, and calibration curves.
resultIn the NHANES dataset, univariate analysis indicated a significant correlation between creatinine levels and endometriosis (OR = 1.01, 95% CI: 1.00-1.01, P = 0.0048), while multivariate analysis maintained significant results after adjustment (OR = 1.00, 95% CI: 1.00-1.01, P = 0.0431). Bidirectional MR analysis demonstrated a causal relationship between creatinine levels and endometriosis, with a positive IVW result of 1.001 (95% CI: 1.00-1.002, P = 0.0350). In the chinese tertiary hospital dataset, the AUC for the diagnostic model on both training and validation sets were 0.721 and 0.730, respectively. An increase of 10 μmol/L in creatinine levels raised the risk of endometriosis by approximately 8% (OR = 1.08, 95% CI: 1.07-1.09, P < 0.001).
conclusionThis study establishes a significant link between creatinine levels and endometriosis, confirming creatinine as an independent risk factor. Elevated creatinine levels could be used as non-invasive biomarkers for the early detection and diagnosis of endometriosis. Future research should aim to validate these findings in larger, multicenter studies and delve into the specific biological mechanisms, paving the way for novel therapeutic strategies.
