Episodic memory performance in a multi-ethnic longitudinal study of 13,037 elderly - Fig 1

Episodic memory trajectories considering non-cognitively impaired subjects (two upper panels) and all subjects (two lower panels) at baseline within each of the study cohorts. NHW: Non-Hispanic Whites; AfAm: African-Americans; CH: Caribbean-Hispanics. The X-axis correspond to the time of follow-up in years (ranging from 0 to 15); the Y-axis correspond to the residual episodic memory score (ranging from -6 to 4) after being adjusted for sex, age, education, episodic memory scores at baseline and total years of follow-up (truncated to a maximum of 15 years).
