Table 2.
Task | Normal Elderly (n = 11) | MCI (n = 9) | AD (n = 9) |
---|---|---|---|
Memory* | 3.9 (3.3, 4.4) | 2.4 (1.9, 3.0) | 2.6 (1.6, 3.7) |
Sensory | 5.5 (3.0, 5.7) | 3.5 (3.3, 5.4) | 7.6 (6.0, 10.0) |
p < .05
Values in the table are median and interquartile range, expressed as area × 10−3. Since the TPF and 1-FPF are proportions, they are unitless and the area under the curve (AUC) is also unitless. Pairwise comparisons were completed between each clinical group for both tasks. There was a significant difference between the Normals and MCIs (Rank Sum Test one-sided p = .03) and Normals and ADs (Rank Sum Test one-sided p = .04) for the memory task, but not between the MCIs and ADs. The difference between the groups on the sensory task was not significant.
