Growth parameters	n	Extremely preterm Mean (SD)	Comparison Mean (SD)	Difference in means (CI)
OFC SDS	239/160	−1.63 (1.29)	−0.33 (1.02)	−1.3 (−1.5 to 1.1)
Weight SDS	241/159	−1.18 (1.34)	0.07 (1.18)	−1.2 (−1.5 to 1.0)
Height SDS	237/159	−0.95 (1.12)	−0.00 (1.08)	−0.95 (−1.2 to 0.7)
BMI SDS	237/158	−0.87 (1.30)	0.11 (1.14)	−0.98 (−1.2 to 0.7)

BMI, body mass index; OFC, occipito-frontal head circumference; SDS, standard deviation score.
