Outcomes
As per the AASLD 2018 guidelines on hepatitis B, the presence of positive HBV core antibody (anti-HBc) serves as an indicator of HBV infection, including previous or present infection[18]. A detailed description for anti-HBc detection has been reported in previous study[4]. Positive anti-HBc was classified under the ”yes” group for HBV infection, while negative anti-HBc was categorized under the ”no” group.
