Left average depth | 0.59 ± 0.09 | 10−7 | 6% |
Right average depth | 0.41 ± 0.11 | 10−5 | 6% |
Left average length | 0.47 ± 0.12 | 5 × 10−6 | 4% |
Right average length | 0.60 ± 0.12 | 3 × 10−7 | 3% |
Global phenotypes were calculated by averaging CS measurements from both hemispheres; hemispheric phenotypes were calculated by averaging measurements from each hemisphere separately.
aVariance explained by demographic covariates: age, age2, sex, age × sex, and age2 × sex, which were included in all genetic analyses.
