Figure 1. Hepatocellular carcinoma-free survival rate by different interferon-based treatment conditions as estimated by the Cox proportional hazards model in patients with hepatitis C viral infection.

Figure 1

<6 months IBT vs. no treatment, p = 0.264; ≧6 months IBT vs. no treatment, p = 0.006. IBT = interferon-based treatment. The y-axis is modified, so that it only displays the survival estimates between 0.94 and 1.00.
