Figure 1 Correlation analysis. Correlation analysis between the expected hepatitis B virus (HBV) DNA concentration (log IU/mL) in the sensitivity references (standards) and the corresponding test results in the Abbott (A) and Da-an (B) assays. Each point represents the mean log IU/mL of three data points tested over 3 d.

Figure 2 Bland-Altman analysis. Bland-Altman analysis of hepatitis B virus (HBV) DNA level measured with the Abbott and Da-an assays in seven sensitivity references of HBV DNA standards. The difference between the Abbott and Da-an measurements is plotted as a function of the mean of the two values. The area between the dashed lines corresponds to the mean difference ± 1.96 SD.

Figure 3 Correlation analysis. Correlation analysis between hepatitis B virus (HBV) DNA levels tested with the Abbott and Da-an assays in 126 paired serum samples of patients with chronic hepatitis B. HBV DNA levels (log IU/mL) measured with Da-an assay were plotted against viral load (log IU/mL) determined with the Abbott assay.

Figure 4 Bland-Altman analysis. Bland-Altman analysis of hepatitis B virus (HBV) DNA level measured with the Abbott and Da-an assays in 126 clinical serum samples from patients with chronic hepatitis B. The difference between the Abbott and Da-an measurements is plotted as a function of the mean of the two values. The area between the dashed lines corresponds to the mean difference ± 1.96 SD.
