Relationship Between BMI-Z and Dose Delivered at Each Time Point

	4-Month child BMI-Z (n = 112)			7-Month child BMI-Z (n = 107)			12-Month child BMI-Z (n = 106)

Estimates are from regression models adjusting for baseline value of the outcome variable, child gender, and child age at baseline. Control group has 0 for both dose modalities.
