Figure.3. False recent ratio of HCV Genedia-Avidity by avidity index.
Subject-level False Recent Ratios (FRR) calculated by estimating the probability of appearing recent using an exact binomial test and 95%CIs determined from a binomial distribution are shown by avidity index (AI) cutoffs in increments of 10%. (A) The FRR (solid line) and 95%CI (dashed lines) for 1541 samples from 794 individuals. (B) The FRR for 426 genotype (GT) 1 samples from 208 individuals (light grey), and 723 GT3 samples from 291 individuals (dark grey). (C) The FRR for 1091 HIV-uninfected samples from 578 individuals (light grey), and 449 HIV-infected samples from 218 individuals (dark grey). (D) The FRR for 274 HIV-infected samples from 163 individuals with a CD4 T-cell count ≥200 (light grey), and 76 HIV-infected samples from 63 individuals with a CD4 T-cell count <200 (dark grey).
