Scatter plot including mean regression line for anthropometric measurements of all study infants (n = 96) as a function of gestational age (GA) in weeks. Nude weight g = -2736 + 137.97 GA, r = 0.75, p < 0.001. Length cm = 21.7 + 0.63 GA, r = 0.65, p < 0.001. Head circumference (HC) cm = 12.3 + 0.55 GA, r = 0.64, p < 0.001.
