Subsequently, two-sample Mendelian randomization (MR) analyses were conducted using inverse variance weighting (IVW), Egger regression (MR-Egger), and weighted median (WM) methods. Heterogeneity was evaluated using Cochran’s Q test, and in case of detected outliers, they were removed for re-evaluation of MR causality.Results: From the endometriosis GWAS dataset, 33 single nucleotide polymorphisms (SNPs) were selected as instrumental variables. All three methods, IVW (OR = 1.39, P < 1× 10− 8), MR-Egger (OR = 1.41, P = 0.003), and WM (OR = 1.37, P = 1.16× 10− 5) confirmed a causal relationship between endometriosis and PID. The association between endometriosis and pelvic inflammation remained unaffected by the exclusion of individual SNPs. Lastly, Cochran’s Q test and funnel plots showed no evidence of SNP asymmetry.Conclusion: The results of the MR analysis support a potential causal relationship between endometriosis and an increased risk of PID.Keywords: endometriosis, pelvic inflammatory diseases, genome-wide association study, Mendelian randomization |
