| Deletion size | − .092 | .723 |

| ADOS comparison score | − .379 | .150 |
| RBS-R total score | .545 | .011* |
| NVIQ | .618 | .543 |
| Phase bias versus | – | – |
| Age | .194 | .342 |
| Vineland adaptive behavior | − .104 | .630 |
| Vineland socialization | − .202 | .343 |
| Deletion size | .232 | .261 |
| SSP total | .367 | .100 |

All tests were performed as linear regressions, with age included as a control variable for all subsequent tests. A Benjamini–Hochberg correction was applied to ln(z-MI) and phase bias comparisons separately. * indicates significance (FDR = .1)
