SECONDARY outcome

Timeframe: week 12

Population: Values were only available in 154 patients.

Change in quantitative HBs antigen at week 12. The data were log transformed before analysis and the changes to baseline were analysed. Therefore, the reported values might be interpreted as percentage changes. Lower scores mean a better outcome.
