Figure. Association of PTSD With Rate of Cognitive Change and Fitted Linear Trajectories by Posttraumatic Stress Disorder (PTSD) Group.

The β coefficients are from models adjusted for age at baseline cognitive assessment, race and ethnicity, parental educational level, participant educational level, and number of previous cognitive tests. Error bars represent 95% CIs. Fitted linear trajectories were calculated for non-Hispanic White women (the largest race and ethnicity group in this sample) who were aged 61 years at baseline, with the highest participant educational level of bachelor’s degree and the highest parental educational level of high school.
