November, 1989: The first RCTsDavis, et al., N Engl J Med; 321: 1501-6.
Complete response (normal ALT at week 24):
1 MU group 9/57 (16%); p=0.01
untreated group 2/51 (4%); p=0.001
- NNT with 3 MU IFN vs. no treatment to achieve complete response at week 24 = 3.
- Histologic improvement in 52% of 3 MU group vs. 29% of 1 MU group, but histological and biochemical response did not correlate.
- 48 % had biochemical relapse by mean f/u of 17 wks.
