↵a P < .05 for 2-sided t test comparing preterm infants at 40 weeks with term-born controls (PPREMO). Continuous variables are given as median ± interquartile range (range). Scans with poor quality (PPREMO, n = 39), realignment errors (PPREMO, n = 1; dHCP, n = 39), and severe pathology (PPREMO, n = 16; dHCP, n = 12) were excluded.
