ABO blood group-dependent association of serum retinol-binding protein 4 with eosinophilic inflammation and spirometric parameters in adults with asthma.
Growing evidence links retinol binding protein-4 (RBP4) to inflammation; however, its association with inflammatory cell indices and spirometric parameters in asthma remains unclear, and the potential modifying role of ABO blood group has yet to be explored. The main aim was to assess the associations of serum RBP4 wit...
