The construction of confidence intervals to estimate π1 - π2, the difference of two proportions, is an importante problem in applied work. We review different methods to construct them and we analyze their performance by a simulation study. Also we propose a index that allows us to compare these procedures, analyzing simultaneously the real confidence level and the length of them.
