The inverse variance weighting (IVW) method served as the primary analytical approach.

Using the IVW method, we also discovered that characteristic indicators of PCOS, including decreased high\u2010density lipoprotein (HDL) levels, increased body mass index (BMI), and elevated fasting insulin levels, pose a risk for PE. At the same time, there is no clear causal relationship between low\u2010density lipoprotein (LDL), total cholesterol (TC), triglycerides (TGs), testosterone (T), fasting blood glucose (FBG), and circulating sex hormone\u2013binding globulin (SHBG) and PE.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Our research results provide new evidence at the genetic prediction level for PCOS as a risk factor for PE.
