| Full trisomy (N = 116) | Mosaicism (N = 13) | β(p) | |
|---|---|---|---|
| Centiloid | |||
| Mean (SD) | 50.55 (36.84) | 61.88 (34.6) | −0.687 (0.94) |
| Range | −19.19–156.71 | 7.13–144.15 | |
| Full trisomy (N = 50) | Mosaic (N = 4) | β(p) | |
| Tau (Mayo Composite) | |||
| Mean (SD) | 1.3 (0.33) | 1.49 (0.36) | 0.259 (0.097) |
| Range | 0.99–2.3 | 1.1–1.96 | |
