Statistical power analysis

True rates [%]			Sample size per group (including dropouts)a	Power for the respective test setting [%]
πFMT	πFMFT	πPlacebo		Global testb	FMT and FMFT vs. placebo	FMT or FMFT vs. placebo
30	30	5	58	93	98	92
30	40	10	58	92	95	69 rsp 95
40	40	10	58	96	99	95

^aResulting in a total sample size would be 3 × 58 = 174, 3 × 93 = 279, and 3 × 50 = 150 patients to be randomized

^bThe increased power (i.e., a power larger than 80%) results from the inclusion of dropouts in the analysis
