Fagan’s nomograms for Abbott ARCHITECT HCV Ag assay. This figure shows Fagan’s nomograms illustrating the post-test probability of active HCV infection in HCV/HBV coinfected individuals using the Abbott ARCHITECT HCV Ag assay compared to a confirmatory nucleic acid test at various pre-test probability levels. Each panel represents a different pre-test prevalence of HCV infection: (A), 0.1% (B), 0.5% (C), 1% (D), 5%, (E) 10%, and (F) 15%. DLR diagnostic likelihood ratio; HBV hepatitis B virus; HCV hepatitis C virus; NLR negative likelihood ratio; PLR positive likelihood ratio; Post-tp post-test probability; Pre-tp pre-test probability
