Characteristics of the study population.

<p>Abbreviations: ALT, alanine aminotransferase; ARV, antiretroviral; HBe-Ag, Hepatitis B envelope antigen; HBsAg, Hepatitis B surface antigen; HCV, Hepatitis C virus; y, years.</p><p>Data are presented as median (interquartile range) for continuous variables and as count (column percentage) for categorical variables. P values hypothesis testing between HBsAg positive and HBsAg negative are derived from Mann-Whitney U test for continuous and χ2-test for categorical variables.</p

Test characteristics of Determine HBsAg determined in comparison with a reference test in adult and antiretroviral-naïve HIV-1 positive patients in Ifakara, Tanzania.

<p>Abbreviations: CI, confidence interval; FN, false negative; FP, false positive; NPV, negative predictive value; PPV, positive predictive value; TN, true negative; TP, true positive. Agreement is measured between two independent readings of Determine HBsAg.</p
