Estimates and 95% confidence intervals for BMI-SDS from two to six years – results from a multilevel mixed-effects linear regression model including group (n = 171), age and sex of the child; pre-pregnancy BMI of the mother, and interaction between group and age of the child

	Coefficient (95% CI)	p-value
Group (ref. = control)	−0.02 (− 0.70 to 0.65)	0.94
Age of the child	−0.23 (− 0.44 to 0.02)	0.03
Age of the child2	0.03 (0.00 to 0.05)	0.04
Group * Age of the child	0.02 (−0.28 to 0.32)	0.89
Group * Age of the child2	−0.00 (− 0.04 to 0.03)	0.81
Maternal pre-pregnancy BMI	0.01 (0.00 to 0.03)	0.02
Sex of the child	−0.02 (− 0.32 to 0.28)	0.88
Constant	−0.41 (−1.38 to 0.55)	0.40
