Odds ratios from logistic regression models after adjusting for age, education and sex.
| Groups compared | term | OR (95% CI) | p |
|---|---|---|---|
| CU A−T− vs. CU A+T+ | CBB Lrn/WM composite z 1 unit less | 1.25 (0.78, 2.05) | 0.35 |
| CU A−T− vs. CU A+T− | CBB Lrn/WM composite z 1 unit less | 1.03 (0.74, 1.46) | 0.85 |
| CU A−T− vs. CU A+T+ | AVLT Delay z 1 unit less1 | 1.54 (0.96, 2.53) | 0.08 |
| CU A−T− vs. CU A+T− | AVLT Delay z 1 unit less1 | 1.58 (1.07, 2.39) | 0.03 |
Note. For logistic regression analyses, AVLT delayed recall scaled score was rescaled to z-score units to aid interpretation. For every 1.0 z-score less, the odds of being in the biomarker positive group increases by the OR reported above. A = amyloid; T = tau; CU = Cognitively Unimpaired; CBB = Cogstate Brief Battery; AVLT = Auditory Verbal Learning Test 30-Minute Delayed Recall.
