Note: Analyses are identical to Table 4 except all individuals with MCI at the ECog assessment were excluded from analyses. The Intercept and Slope factors refer to the latent growth curve model of episodic memory (A) or executive function (B). Estimates for participant- and informant-rated decline were estimated in the same model, but their associations with memory and executive function were estimated in separate models because memory and executive function abilities were too highly correlated to be included in the same model. All estimates are standardized. N=1427
