Breastfeeding and clinical outcome	Neurodevelopment		p-value
	Normal for age (n = 42)	Delayed for age (n = 42)
Exclusive breastfeeding at 6 months	26 (61.9)	23 (54.8)	0.507
Hospital admissions	4 (9.5)	5(11.9)	0.500
Neurological abnormalities	24 (57.1)	32 (76.2)	0.064
HC at the last Bayley evaluation	47.4 (2.2)	47.7 (1.6)	0.387
HC Z-score at the last Bayley evaluation	0.9 (1.0)	0.7 (1.0)	0.458
Delta HC	-0.1 (1.3)	0.1 (1.1)	0.007

HC: head circumference; Delta Z-score HC: difference between Z-score HC mean at last examination and at birth.
