DTI TBSS results for the comparison of FA values between 2-week-old neonates born by cesarean delivery or vaginal delivery in cohort 1. DTI TBSS results for the comparison of FA values between 2-week-old neonates born by cesarean delivery or vaginal delivery in cohort 1. Green represents major white matter tracts in the brain; orange shows voxels that have different FA values between groups. A, Group differences (P < .05, corrected for the voxelwise multiple comparisons) when no covariates were added. B, Group differences (P < .05, corrected for the voxelwise multiple comparisons) when 3 demographic parameters that were different between groups (gestational weight gain, infant sex, and birth length) were added as covariates. C, Trend of group differences (P < .15, corrected for the voxelwise multiple comparisons) when an additional 2 potential confounders (gestational age at MR imaging and maternal BMI at early pregnancy) were included as covariates. D, Illustration of ROIs (red outlined) selected for further post hoc analysis. E, Group comparison of mean FA values in these white matter ROIs.
