Association of serum hepatitis B surface antigen with hepatitis B virus DNA and hepatic function in patients with chronic hepatitis B

Table 2 Diagnostic performance of hepatitis B surface antigen thresholds for predicting high viral load and significant liver injury

Indicators	Cut-off	AUC	95%CI	Specificity (%)	Sensitivity (%)	P value
High viral load	> 4.09	0.868	0.798-0.937	78.67	88.57	< 0.001
Significant liver injury	> 4.07	0.821	0.724-0.917	90.91	69.70	< 0.001

AUC: Area under the curve; CI: Confidence interval.
