Fig. 6. Percentage of lung located under the heart relative to total lung area. Median values (25th, 50th, and 75th percentiles) and largest and smallest values that are not outliers are reported. Outliers (cases with values between 1.5 and 3 box lengths from the upper or lower edge of the box) are presented as closed circles. *P < 0.05 versus section 1, †P < 0.05 versus sections 1 and 2, ‡P < 0.05 versus sections 1, 2, and 3, all by Student-Newman-Keuls method.
