  1. Adj = adjusted, CI = confidence, OR = odds ratio. PRS = polygenic risk scores. ORs and 95% CI were calculated using binary logistic regression model, adjusted for PC1, PC2, PC3 and PC4. The calculations with isolated/spread endometriosis, no GI-symptoms/GI-symptoms and no hormone/hormone therapy were also adjusted for age. The calculations with no GI-symptoms/GI-symptoms was also adjusted for hormone therapy. Fisher´s exact test was used to calculate the distribution of PRS quartiles among groups. P-values < 0.05 were considered statistically significant
