What are ways that investigators can plan for study design changes as data accumulates? The authors present Learn-As-you-GO (LAGO) for an adaptive method to apply in stages during a study, and compare against other adaptive designs for trials such as Sequential Multiple Assignment Randomized Trial (SMART) design and Multiphase Optimization Strategy (MOST). Methods are illustrated through the Better Birth Study.
