TABLE 3.
Percentage difference and post hoc Tukey p‐values for genotype and age effects on PS w and PS g in the composite ROI
| Genotype effects (WT vs. TgF344‐AD) | PS w | PS g | ||
|---|---|---|---|---|
| % difference | p‐value | % difference | p‐value | |
| 13 months | +14 | 0.82 | −15 | 0.40 |
| 18 months | +72 | 0.012 | −10 | 0.99 |
| 21 months | +2.9 | 1.00 | +29 | 0.82 |
| Age effects (WT) | ||||
| 13m vs. 18m | −4.9 | 0.99 | +10 | 0.99 |
| 18m vs. 21m | +124 | 0.050 | −11 | 0.99 |
| 13m vs. 21m | +113 | 0.042 | −2 | 1.00 |
| Age effects (TgF344‐AD) | ||||
| 13m vs. 18m‐ | +43 | 0.027 | +17 | 0.91 |
| 18m vs. 21m | +34 | 0.50 | +31 | 0.71 |
| 13m vs. 21m | +93 | 0.047 | +53 | 0.21 |
Positive percentage differences indicate higher values in TgF344‐AD rats (genotype effects) or in older rats (age effects). Negative percentage differences indicate higher values in wild‐types (WTs) (genotype effects) or in younger rats (age effects). Bold indicates significant effects at the 5% level
