Following significant correlation within IUGR fetuses (P<0.05),
regressions on separate treatment groups were found to be not significantly
different, and a single regression was fit between circulating cortisol and A)
LV binucleate width (Y=−1.604X+13.21, r2=0.2778,
P=0.0098), and B) RV binucleate length
(Y=−6.587X+91.76, r2=0.2031, P=0.0353).
Linear regression±95% confidence intervals are plotted with raw data.
