%X Probability of stopping for futility and overall power for Approach 3. Plot of probability of stopping for futility (left figure) and overall power (right figure) for Approach 3 using the futility β γ-boundaries α f CE = 0.69 $ \alpha_{f}^{CE}=0.69$ and α f MC = 0.65 $ \alpha_{f}^{MC}=0.65$ for composite endpoint and main component, respectively.
