  • RF, rheumatoid factor; ALT, alanine amino transferase; HCV, hepatitis C virus.

  • *Except where indicated otherwise, values are the median (ranges) and at baseline.

  • †Liver necroinflammation and fibrosis were graded according to the Metavir scoring system. ‡HCV RNA (month +3) was evaluated 3 months after the start of antiviral treatment.
