PRIMARY outcome

Timeframe: 24 months

Responses were evaluated according to criteria modified from those developed by Blade et al., 1998 The reference point for evaluating response improvement is the baseline. This baseline reference point is also valid when a patient has already achieved a response and transitions through into a better response grade.
