Figure 3. Comparison the change point with the clinical diagnoses (the incident amnestic MCI or AD group).

Figure 3

Panel A: Posterior distribution of the change point. The solid curve is a kernel density estimate of the change point, in years since enrollment. The dashed curve is the density estimate of the first clinical diagnosis of amnestic MCI. Panel B: Scatter plot of time of clinical amnestic MCI diagnosis versus the change point. On the horizontal axis is the estimated change point, in years since enrollment. On the vertical axis is the corresponding clinical diagnosis of amnestic MCI. The plot is overlaid with a 45-degree reference line. Panel C: Histogram of difference between change point with clinical diagnosis, overlaid with a normal density.
