Course of development of 3 forms of nonsynostotic plagiocephaly in intervention and control group infants. Legend: The proportion of infants with brachycephaly increased between 2 and 4 months and then began to decrease in both groups. The proportion of intervention group infants with plagiocephaly began to decrease between 2 and 4 months and stayed low, while the proportion of control group infants with plagiocephaly began to decrease after 4 months. The proportion of intervention group infants with combined plagiocephaly/brachycephaly began to decrease between 2 and 4 months and stayed low, while the proportion of control group infants increased slightly between 2 and 4 months and began to decrease after 4 months
