Equations for prediction of echocardiographic parameters in fetuses with left CDH that survived after birth.

Parameter	Coefficient (β)*	Constant	Root MSE	Adjusted R2
MV diameter (n = 92)	1.2883	−4.6913	0.1521	0.62
AV diameter (n = 87)	1.1508	−4.8060	0.1513	0.57
LV length (n = 90)	1.1145	−3.1666	0.1771	0.47
LV width (n = 81)	1.3237	−5.3737	0.3022	0.31
TV diameter (n = 92)	1.2398	−4.2647	0.1702	0.54
PV diameter (n = 89)	1.2327	−4.6852	0.1256	0.68

Mean predicted value = exp [(β * gestational age) + constant].

MV, mitral valve; AV, aortic valve; LV, left ventricle; TV, tricuspid valve; PV, pulmonic valve.

*All coefficients were statistically significant (p < 0.001).
