From: Bayesian adaptive designs for multi-arm trials: an orthopaedic case study
Average sample sizes (a, c, e, g, i, k) and probability of trial success (Pr(Success); b, d, f, h, j) for each design. Each row represents a different scenario: a, b “Null” scenario; c, d “One works, 10 more”; e, f “One works, 5 more”; g, h “Better, Best”; i, j “One worse, others work”; k, l “All work, two similar”. The type I error is represented in b; The power is given in d, f, h, j, l
