Based on data from the Pediatrix Medical Group from close to 400,000 infants born in 248 US hospitals from 1998-2006. Comparison to curves used since the 1970s suggests that more modern curves are much more valid to judge growth of premature infants today.

Do We Need Another Set of Growth Charts for Premature Infants?

A discussion about the use of various newer premature-infant growth curves. A survival improves, curves tend to include smaller infants. There are also methodological differences in how growth points are compiled for these charts that generate small differences in percentiles.
