FETUB and polycystic ovary syndrome: Importantly, after three months treatment with GLP-1RA, serum Fetuin-B concentrations in PCOS women showed a downward trend, while after six months of GLP-1RA treatment, serum Fetuin-B levels were markedly decreased (from 9.22 ± 0.77 at pretreatment to 8.23 ± 0.54 at posttreatment three months, and finally to 7.27 ± 0.46 mg/L, p < 0.05 for posttreatment six months vs. pretreatment; Figure 3(c)).
