From: A radiographic measurement of left atrial size in dogs
Boxplots comparing radiographic left atrial dimension (RLAD) and vertebral heart size (VHS) measures for groups with absence (Group 1, n = 31) or presence (Group 2, n = 46) of left atrial enlargement defined as La/Ao > 1.6. The box shows the median and quartiles and the whiskers represent the range or 1.5 times inter-quartile range in the presence of outliers
