Circulating cytokines levels and the risk of polycystic ovary syndrome: A Mendelian randomization analysis.

ABSTRACT: This study utilized Mendelian randomization (MR) analysis to explore the causal relationship between circulating cytokines and polycystic ovary syndrome (PCOS), and to identify potential biomarkers of PCOS mechanisms. Genetic instrumental variables for cytokines were derived from 2 large-scale genome-wide association studies (GWAS) involving 8293 and 14,824 European participants. Summary statistics from a GWAS meta-analysis (10,074 PCOS cases and 103,164 controls of European ancestry) were used in the discovery phase of MR analysis. Replication analysis utilized another GWAS meta-analysis dataset (3609 cases and 229,788 controls). The primary analysis employed the inverse-variance weighted (IVW) method, with secondary methods including constrained maximum likelihood model averaging, weight
