PRDFS rates and exact 95% confidence intervals after 12 months of treatment with Viscum or Etoposide, respectively. The horizontal line represents the 12% PRDFS rate derived from historical controls. By crossing the 12% line, the Etoposide confidence interval indicates that this treatment cannot statistically be distinguished from the historical rate, whereas for Viscum a significant difference can be deduced.
