Boxplots of echo variables a RV stroke volume, b LV stroke volume, c 2D global longitudinal RV strain, and d LVEDV, at baseline and at week 26 (Echo subgroup, N = 45). The box plots show the median (line), mean (X), and the first and third quartiles (outer box borders). The upper and lower whiskers represent the location of the maximum and minimum within the first and third quartiles ± 1.5 times the interquartile range. The circle represents outliers.
