Figure 2.

Association between thoracic aortic diameters determined by transabdominal ultrasonography and newborn body weight in CONTROL (n = 8), HIGH-RISK (n = 3), and CLONED pregnancies (n = 3). This figure represents the 14 cases in which both the fetal aortic diameter (Ao) and the birth weight (BW) were available. The regression curve has been drawn on the graphs for the fetuses of CONTROL (♦) pregnancies in which a positive correlation (R = 0.62; P = 0.01) between Ao and BW was observed. Fetuses from the CONTROL (♦), HIGH-RISK (▪), and CLONED groups (▴) are represented. No association was found between Ao and BW in fetuses from HIGH-RISK or CLONED group.
