Fig. 1From: An adaptive two-arm clinical trial using early endpoints to inform decision making: design for a study of sub-acromial spacers for repair of rotator cuff tendon tearsRecruitment, data and information accrual during follow-up. Expected recruitment, data and information accrual during 24 months, estimated from simulations. Information accrual is plotted for three possible correlation models: ρ12=ρ13=ρ23=0.5, ρ12=ρ13=ρ23=0 and, ρ12=ρ13=0 and ρ23=1Back to article page
