Plot of postnatal growth rate of length of CC related to length of CC at term equivalency in 64 very premature infants born at 23–33 weeks gestation. Growth rate is from birth to term equivalency. The CC was measured at cranial sonography. The slower the CC grows, the shorter it tends to be at term equivalency (linear regression R2 = 0.39). Symbols correspond to n-week gestation.
