Difference scores for physical characteristics between baseline and 6 or 12 months

Time	Characteristic	Intervention (n = 152)	Control (n = 69)
6 months	Height (cm)	3.63 ± 0.41	3.13 ± 0.39
	Weight (kg)	1.31 ± 0.35	1.58 ± 0.33
	zBMI	−0.211 ± 0.005*	−0.173 ± 0.004
12 months	Height (cm)	5.64 ± 0.88	5.07 ± 0.92
	Weight (kg)	3.94 ± 0.48*	4.43 ± 0.45
	zBMI	−0.105 ± 0.004*	−0.068 ± 0.006

zBMI, standardised body mass index. Values represent the mean difference score from baseline ± standard deviation. *indicates different from control (P < 0.05).
