From: Modeling the course of Alzheimer's disease to improve clinical trials: symposium report
Correspondence between the model-based forecasted data and the actually observed neuropsychological data. Correspondence of predicted (shaded boxes) and observed (clear boxes) results on a battery composed of nine neuropsychological battery tests (NP-Batt9). Boxplots show averaged z-scores as a function of time. The consistent small overestimation of decline in the forecasted values is ascribed to selective dropout of patients with more advanced Alzheimer's disease in the observed sample.
