Total intervention effect as estimated by the joint model for CDR-SB. The total intervention effect on the hazard of dementia diagnosis as estimated from the joint model (solid line) and Cox model (dashed line) for CDR-SB, in a without and in b with correction for baseline MMSE in the survival sub-model. Corresponding 95% percentile confidence bands (light grey corresponding to the joint model and dark grey corresponding to the Cox model) were based on 2500 bootstrap samples
