Figure 1. Fitted and observed trajectories of jointly modelled episodic memory and B-SIT scores. Scales are z-scores (mean 0, SD 1). (A) The trajectories of the entire sample (n= 1023; (B) Latent Class 1-Stable average (n= 690, 67.4%); (C) Latent Class 2- Stable EM/OI decline (n= 231, 22.6%); (D) Latent Class 3- Joint decline (n= 102, 10.0%). The mean trajectories of each plot are shown in bold.
