Fig. 3From: Evaluation of right ventricular function in fetuses with isolated single umbilical artery using spatiotemporal image correlation M-modeScatterplots, with isolated SUA, of the correlations between the birth weight and spatiotemporal image correlation (STIC) M-mode fetal tricuspid annular plane systolic excursion (f-TAPSE) against: (Control) estimated birth weight (regression line:0.1734 × f-TAPSE+ 2.006 R2 = 0.4630); and (isolated SUA) estimated birth weight (regression line: Y = 0.2371 × f-TAPSE + 1.407 R2 = 0.623)Back to article page
