Demographics and baseline cognitive measures by group.
| Variable | Control (n = 68) | aMCI (n = 133) | Mean difference (95% CI) t-test or Χ² (d.f.) |
|---|---|---|---|
| Age (years (se)) | 68.4 (1.1) | 77.6 (0.6) | −9.2 (−11.6 to −6.8), P <0.0001 |
| Gender female (n (%)) | 47 (69%) | 52 (39%) | Χ²(1) = 16.2, P <0.001 |
| APOE- ε4 present (n (%) | 17 (27%) | 56 (46%) | Χ²(1) = 6.0, P = 0.014 |
| FCSRT-IR (mean (s.e.) | 47.6 (0.1) | 39.0 (0.8) | 8.6 (6.3 to 11.0), P <0.0001 |
| MOCA (mean (s.e.) | 28.0 (0.2) | 22.9 (0.2) | 5.1 (4.4 to 5.8), P <0.0001 |
ApoE ε4 = Apolipoprotein E ε4 allele carrier; MOCA = Montreal Cognitive Assessment; FCSRT-IR = Free and Cued Selective Reminding Test with immediate recall.
