Consequently, this study conducted MR analyses on two samples to elucidate the potential impact of genetically predicted levels of six adipokines [Adiponectin, Leptin, Soluble leptin receptor (sOB-R), Resistin, Retinol-binding protein 4 (RBP4), and plasminogen activator inhibitor 1 (PAI-1)] on lung disease. The gene discussed is RBP4; the disease is lung disorder.
