Figure 2.

Hepatitis C virus (HCV) RNA viral kinetic plots for those who did not achieve sustained virologic response (SVR) 12 (N = 7). HCV RNA (in log₁₀ IU/mL) is shown on the y-axis and study follow-up visits are shown on the x-axis.

Legend: open markers = detectable HCV RNA; closed markers = undetectable HCV RNA log₁₀ HCV RNA; reference line = 1.15 log₁₀ IU/mL = undetectable HCV RNA; study week reference line = HCV end of therapy. Abbreviations: EOT, end of treatment; HCV, hepatitis C virus.

*Participant with EOT+24 weeks HCV RNA < LLOQ (lower limit of quantification) began ledipasvir-sofosbuvir 28 days after EOT+12 weeks visit and received 56 days of ledipasvir-sofosbuvir before going off study.

**Participant with EOT+24 weeks HCV RNA < LLOQ target not detected began ledipasvir-sofosbuvir 32 days after EOT+12 weeks visit and received 52 days of ledipasvir-sofosbuvir before going off study.
