Figure 7.

Left and right leg thickness measurements using ultrasonography at 37/38 and 27/28 weeks of pregnancy. The differences of five measurements between 37/38 and 27/28 weeks of pregnancy were compared using multivariate correlation analysis, in all combinations. The differences between the left and right leg circumference measurements at 37/38 and 27/28 weeks were positively correlated (r=0.60, p=0.03) and the differences between the left and right leg skin thickness measured using ultrasonography at 37/38 and 27/28 weeks were positively correlated (r=0.61, p=0.03).
