a 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)
