Summary statistics for the samples included in this study
| Control mean (SD) | Case mean (SD) | P value (t-test, Wilcoxon rank sum or regression) | ||
|---|---|---|---|---|
| Gender | Male | 9 | 8 | |
| Female | 2 | 3 | ||
| Age at death | 73.7 (1.01) | 77.7 (4.67) | 0.012 | |
| Post-mortem delay | 34.5 (13.6) | 64.5 (24.7) | 0.007 | |
| Braak stage | 1.45 (1.21) | 1.90 (0.99) | 0.382 | |
| Temporal SVD score | 0.75 (0.50) | 1.57 (1.27) | ||
| Synaptophysin (ng/μl) | 3.85 (2.68) | 2.38 (0.75) | 0.622 | |
| Drebrin (ng/μl) | 5.47 (3.46) | 8.38 (1.98) | 0.020 | |
| SNAP-25 (ng/μl) | 0.0373 (0.166) | 0.0236 (0.0045) | 0.024 | |
| PSD-95 (ng/μl) | 0.411 (0.334) | 0.480 (0.345) | 0.876 | |
| VEGF (μg/μl) | 0.573 (0.328) | 0.830 (0.267) | 0.058 | |
As can be seen, the cases were older than the controls and had a greater mean post-mortem delay.
