From: Foetal aortic flow velocity waveforms in healthy and hypertensive pregnant women
Predicted mean resistance (RI) and pulsatility (PI) indexes of foetal aorta along pregnancy in normotensive (dashed line, circles) and hypertensive (solid line, triangles) women. The vessel exhibits a gestational age-related increase in both indexes, but there is a noteworthy divergence of PI when groups are compared. Statistically significant differences amongst mean predicted values were found for time 2 and 3 (for time 3, is it clear from the numbers that confidence intervals just below 95% confidence level would not intersect each other). For RI and NT, CI95%: (0.821, 0.842), (0.846, 0.859), (0.856, 0.875) for time 1, 2 and 3, respectively; For RI and HT, CI95%: (0.793, 0.819), (0.834, 0.851), (0.852, 0.877) for time 1, 2 and 3, resp.; For PI and NT, CI95%: (1.780, 1.882), (2.035, 2.107), (2.170, 2.282) for time 1, 2 and 3, resp.; For PI and HT, CI95%: (1.723, 1.842), (1.940, 2.021), (2.044, 2.170) for time 1, 2 and 3, resp.
