We used a two‐sample MR framework to examine the associations of specific adipokines (ie, adiponectin, leptin, sOB‐R and PAI‐1) with five obesity‐related cancers using genetic variants associated with adipokines concentrations from published genome‐wide association studies (GWAS).15, 16, 17, 18, 19. This evidence concerns the gene ADIPOQ and cancer.
