note = "Continuous-wave Doppler studies of the umbilical arteries were performed on 100 women with placenta previa prior to delivery in the third trimester and 100 control subjects matched for gestational age and with normally implanted placentas. The ratio of the maximum (systole [S]) and minimum (diastole [D]) velocities appeared to reflect downstream vascular resistance.",
