Bivariate Correlations of Potential Covariates with Amygdala and Hippocampal Volume.
| Right Hippocampal Volume | Left Hippocampal Volume | Right Amygdala Volume | Left Amygdala Volume | |
|---|---|---|---|---|
| ICV | .670*** | .550*** | .547*** | .534*** |
| Infant age at scan | .407*** | .398*** | .131 | .209* |
| Sex at birth | -.217* | -.126 | -.516*** | -.351** |
| BWP | .282** | .167 | .136 | .300** |
| GAB | .021 | .067 | -.031 | .130 |
| INR | .107 | .047 | .081 | .095 |
| Region-specific QC score | -.03 | .05 | .07 | -.11 |
Note:
ICV = intracranial volume, BWP = birthweight percentile, INR = income to needs ratio, QC = quality control. Infant age at scan was calculated as the sum of gestational age at birth plus weeks from birth to scan.
