VRTX: You're correct; it would be a more logical World!
Not to prolong this, but it is an important point... why is RVR important?
1. If a patient doesn't have RVR at 4 weeks, should they just discontinue?
2. If they have RVR, does that mean they will be cured?
Regardless, the only true indicator at 4 weeks is VR; if a patient has little or no VR at week 4, that is an indication that treatment is fruitless and not worth the 48 weeks.
"91% SVR 24 or SVR 12" is a bit misleading, wouldn't you agree?
