Immediate Recall Scores
MCI	3.59 (3.43, 3.74)	3.21 (3.06, 3.36)	−0.35 (−0.52, −0.19)*	3.90 (3.69, 4.11)	3.81 (3.60, 4.02)	−0.08 (−0.30, 0.15)
Dementia	2.66 (2.41, 2.90)	2.24 (1.99, 2.49)	−0.41 (−0.68, −0.15)*	3.15 (2.70, 3.59)	3.39 (2.94, 3.83)	0.23 (−0.25, 0.71)
Delayed Recall Scores
MCI	1.67 (1.52, 1.82)	1.57 (1.42, 1.71)	−0.10 (−0.24, 0.04)	2.43 (2.23, 2.63)	2.46 (2.25, 2.66)	0.03 (−0.17, 0.22)

Models controlled for participant age and education. Values under Time 1 and Time 2 are model-implied means (95% Confidence Intervals). *Change from Time 1 to Time 2 was significantly different from 0 (p < 0.05).
