ALB and Kawasaki disease: Several studies explored the associations of pre‐albumin (PA)/albumin (ALB) and ALB‐combined indicators (prognostic nutrition index [PNI], albumin‐to‐globulin ratio [AGR], bilirubin‐to‐albumin [BAR], and C‐reactive protein/albumin ratio [CAR]) with intravenous immunoglobulin (IVIG) resistance and coronary artery lesions (CALs) in Kawasaki disease (KD) patients.
