Information is required on two other factors: Statistical significance level. This is often set at 5%. g. ) It is assumed that a mistake would be made by concluding that the new intervention is better than standard treatments, when in fact it is not, so a one-sided significance level is used. In many phase III trials, a two-sided significance level is used, because a mistake is made by concluding that the new intervention is better or worse than the control group, when there really is no difference between them (see Chapter 5).
