From: Nonsynostotic plagiocephaly: a child health care intervention in Skaraborg, Sweden
Decline of nonsynostotic plagiocephaly from 2 to 4 months and 4–12 months in intervention and control group infants. Legend: From 2 to 4 months, the decline in both slopes is steep. The gap in the slopes at 4 months is due to new cases that developed between 2 and 4 months. From 4 to 12 months, the decline in both slopes is less steep but more substantial. There was a decreased rate of reversal in both groups as infants grew older
