James et al measured the foot length of premature neonates and correlated it with other body measures. The authors are from St. Mary's Hospital in Manchester, England.
Subjects: premature infants, presumably English
Parameters:
(1) foot length in cm
(2) birthweight in kilograms
(3) crown-to-heel length (height) in cm
birthweight in kilograms =
= (0.63 * (foot length in cm)) - 2.37
with 95% confidence intervals +/- 0.327 kilograms
crown-to-heel length in cm =
= (4.88 * (foot length in cm)) + 11.23
with 95% confidence intervals +/- 2.3 cm
Rearranging these equations:
foot length =
= (1.587 * ((birthweight) + 2.37)) = (1.587 * (birthweight)) + 3.76
= (0.205 * ((crown-to-rump) - 11.23) = (0.205 * (crown-to-rump)) - 2.302
