Fig. 5From: Evaluation of fetal foramen ovale blood flow by pulsed Doppler ultrasonography combined with spatiotemporal image correlationa Foramen ovale absolute blood flow (QFO) is presented as the 5th, 50th, and 95th percentiles. The equation for the 50th percentile was QFO = -1262.39 + 90.87GA-1.11GA2; r = .93, P < .0001. GA, gestational age. b Regression slopes show a significant correlation between gestational age (GA) and weight-indexed foramen ovale blood volume (iQFO). (Regression slope of iQFO = 629.20 -5.11GA -0.17GA2; r = .84, P < .0001)Back to article page
