Power, you can never have enough of it

  • In randomised trials on the effects of a medical treatment, the power of the trial corresponds to the conditional probability that the conclusion of the trial will be that the treatment is effective, given a certain treatment effect.
  • The time to consider the power of a trial is before conducting the study, to ensure that the design of the trial is such that there is a reasonable chance of demonstrating a clinically relevant effect.
