Effects of age, sex, and education on AUC values.

Age group	Forward selected ROIs	Forward selected ROIs + sex	Forward selected ROIs + education	Forward selected ROIs + sex, education	Forward selected ROIs + age, sex, and education
70–89	0.73	0.74	0.77	0.79	0.79
70s	0.75	0.76	0.78	0.80	0.80
80s	0.88	0.89	0.89	0.90	0.89
90s	0.83	0.83	0.84	0.84	0.85

To assess predictive ability beyond cortical thickness, age, sex, and education were added to logistic regression model.
