The AUROC provided by the multivariate model was 0.950 (95% CI = 0.906-0.993).In addition to previously known ones, the Gc1s/Gc1s phenotype variant of DBP and the unbound fraction of plasma RBP4 may be considered as factors related with the incidence, and possibly the risk, of IR in CHC patients.
Serum RBP4 was measured in 105 treatment-nai ve CHC patients and its correlation with the homeostasis model assessment of insulin resistance index (HOMA-IR), liver histology, virology and metabolic factors was investigated.
