Probability of a significant difference comparing Pulmonary rehabilitation with standard care. The Y-axis shows the probability of a positive result and x-axis shows the required sample size. The colour of lines are as follows BLACK: any difference between groups is considered meaningful RED = a difference of > 25 m is required, GREEN = a difference of > 54 m is required. The broken lines indicate per-protocol analysis with solid lines indicating the intention to treat population
