Abstract

From the results of a positive randomised clinical trial, it cannot be ascertained whether the additional benefit is distributed to all patients or is limited to only a subgroup.We had a new insight: The variance in length of survival in the treated group will be same as the control group if the treatment is effective in every patient; but will be different if the treatment is effective in only a subgroup.
