RETRACTED: Causal effects of omega‐6 and LDL‐C on androgenetic alopecia: A Mendelian randomization study

Abstract Background Increasing studies have reported a causal relationship between androgenetic alopecia (AGA) and lipid‐related metabolites. However, the relationships between HDL‐C, LDL‐C, Omega‐6, and Omega‐3 with AGA remain unclear. Some research findings are even contradictory. Therefore, we designed this study to explore this issue. Methods In this study, we selected seven exposure factors, screened SNPs with significant associations, removed linkage disequilibrium and weak instrumental variables, and conducted bidirectional MR analysis. Results The study found that omega‐6 and LDL‐C, especially total cholesterol in medium LDL and total cholesterol in small LDL, are risk factors for the occurrence of androgenetic alopecia. Conclusion In summary, we found that various lipid‐related metabolites have a causal relationship with the occurrence of androgenetic alopecia, providing new insights into the pathogenesis of androgenetic alopecia and offering references for clinical treatment of androgenetic alopecia.
