Fig 2. Agreement between CRL biometry and the SFH formula.

Fig 2

Reference standard: crown-rump length (CRL) biometry. SFH: symphysis-fundal height. True gestational age determined from CRL biometry. Thick black lines represent the mean bias of the SFH formula in reference to CRL biometry; the thin grey lines represent the 95% limits of agreement. Grey dots are observed values for newborns with normal birthweight for GA (left) or term newborns (right); black dots are observed values for SGA newborns (left) or preterm newborns (right).
