Serum Cav-1 was a pivotal indicator in NAFLD and positively correlated with serum iron-related proteins in volunteers. a Detection of serum total iron, Cav-1, hepcidin, ferritin and Tf concentrations in healthy people (n = 24, the same below) and NAFLD patients (n = 46, the same below). b The AUROC analysis of serum Cav-1, hepcidin, ferritin and Tf levels. c Correlation analysis of serum Cav-1 concentration and serum of total iron, hepcidin, ferritin, and Tf concentration. ^**P < 0.01, ^***P < 0.001, as determined by Student’s t test analysis, Spearman’s rank correlation test or receiver operating characteristic curve analysis. All data were shown as the mean ± SD. AUROC area under the receiver operating characteristic curve, Cav-1 caveolin-1, Tf transferrin, NAFLD non-alcoholic fatty liver disease
