Task: Answer Verification
Input (English): Question: Does ultrasound elastography correlate treatment response by antiviral therapy in patients with chronic hepatitis C?
Answer: With a few exceptions, SVR improved LS. All patients with an increase in LFI were in the non-SVR group, even though LFI decreased in 2 patients. Our findings suggest that an LFI increase indicates lack of treatment efficacy with antiviral therapy. LFI may be useful for the assessment of treatment efficacy in patients with worsening of LS despite achieving SVR with antiviral therapy.
Output (English): yes
