Hepatitis B virus persistent infection-related single nucleotide polymorphisms in HLA regions are associated with viral load in hepatoma families

Figure 3 Second-stage hepatitis B virus viral load. The genetic, nongenetic, and combined risk factors for hepatitis B virus (HBV) viral load were evaluated by area under the receiver operating characteristic curves derived from generalized estimating equation regression models. The difference between the receiver operating characteristic curves of genetic and nongenetic factors was not significant (P = 0.3117). The finding suggests that both factors contributed to the HBV viral load. AUC: Area under the receiver operating characteristic curve.
