Box-whisker plots of lymphatic burden by adverse Fontan status. Lymphatic burden is greater in those with early adverse Fontan status [435 (137–810) vs. 118 (53–207) mL/m2, P = 0.033] (A), late adverse Fontan status [822 (273–1,137) vs. 119 (53–190) mL/m2, P = 0.004] (B), and composite adverse Fontan status [435 (137–822) vs. 114 (51–178) mL/m2, P < 0.001]. Boxes show the 1st to 3rd quartiles, middle line shows the median, and whiskers are set at 1.5 × the interquartile range with dots representing data points beyond the whiskers.
