Coefficients for regression equations relating echocardiographic measurements and BSA

Measurement	Intercept	B	SEE (√MSE)	R²	SW	KS	BP	W
RCA CED	1.506	0.448	0.128	0.484	0.255	0.087	0.471	0.600
LM CED	1.605	0.471	0.134	0.485	0.385	0.200	0.114	0.187
BSA Haycock. (ln[y] = a + bln[x]); Z value = exp((ln[Measurement] – (Intercept + Bln[BSA]))/√MSE)

B: regression coefficient; SEE (√MSE): standard error of the estimate; R²: coefficient of determination; SW: Shapiro-Wilk test; KS: Kolmogorov-Smirnov test; BP: Breusch-Pagan test; W: Wald test
