FIG. 3 — Comparison of Aptima HBV versus cobas HBV (DEFINE cohort). (A) Deming regression analysis of viral load quantification for Aptima HBV versus cobas HBV. (B) Bland−Altman bias plot for measurement of HBV with Aptima and cobas HBV tests. Of the 346 longitudinal observations available from seven selected time points (day 1, weeks 12, 24, 48, 72, 84, and 96), 271 samples with enough remaining volume generated valid results for both tests and are included in these plots.
