Outcome
- Type
- SECONDARY
- Title
- the Negative Predictive Value of Conversion at 2 Weeks for Relapse.
- Description
The Negative Predictive value (and 95% CI) of conversion in the intervention arm will be estimated as the % of relapses among those with a minimum 1 log decline in the number of AFB, or who are already negative or only scanty positive on AFB smear (auramine or FDA).
- Time frame
- at 2 weeks of treatment
- Population
- ITT analysis. This analysis only includes participants in the intervention arm who are negative on auramine smear resp. FDA smear at 2 weeks.
