A composite binary endpoint consisting of the combination of several binary outcomes is often used in the design of a two-arm randomized clinical trial. We present a method to elucidate between a composite binary endpoint and one of its relevant components. This approach is based on the asymptotic relative efficiency (ARE) between two statistical tests to compare the effect of the treatment between two groups. The ARE is expressed in terms of clinical interpretable parameters, such as, t...
