Predicted 5th, 50th, and 95th Percentile Trajectories From Quantile Regression for AV Interval and FHR Across GAs
(A) Fetal echocardiographic atrioventricular (AV) intervals in milliseconds measured by simultaneous mitral inflow and aortic outflow Doppler. Atrioventricular interval versus gestational age (GA) in weeks. Included are the 5th, 50th, and 95th percentiles estimated from quantile regression with natural splines. (B) Fetal heart rate (FHR) in beats per minute versus gestational age in weeks. Included are the 5th, 50th, and 95th percentiles estimated from quantile regression with natural splines. (C) Predicted mean trajectory of fetal echocardiographic atrioventricular intervals in milliseconds over gestational age in weeks at 3 different fetal heart rates in beats per minute (bpm).
