Participant flow chart. Neonate data (180 very preterm-born infants of <32 weeks' gestation, with 1 or 2 MR imaging scanning sessions including DTI) are separated into 3 groups: group 1, 75 neonates with only 1 early scan near the time of birth (median postmenstrual age at scanning, 32 weeks) (all 75 neonates have neurodevelopmental follow-up data at 18-month corrected age); group 2, 78 neonates with 2 scans, both early (PMA, 32 weeks) and at term-equivalent age (PMA, 39.7 weeks) (75 neonates have follow-up data); group 3, 27 neonates with a late scan (PMA, 39 weeks) (16 neonates have follow-up data).
