Fig 1 Right ventricular ejection force versus gestational age for hypoplastic left heart syndrome population (open squares) and normal control population (circles). The quadratic regression line for the normal control population is the dashed line, RVEF = 0.03 (GA)2− 0.25 (GA) − 2.9, R2 = 0.82, whereas the quadratic regression line for the hypoplastic left heart syndrome population is the solid line, RVEF = 0.13 (GA)2− 4.95 (GA) + 50.6, R2= 0.68. The 95% confidence intervals are also illustrated for the normal control population (dashed lines). (GA = gestational age; RVEF = right ventricular ejection force.)
