Representative graphical representations of raw quantitative echocardiographic parameters. (A) Identity plot of end diastolic diameters highlighting extreme outlier (arrow). (B) Histogram of end diastolic diameter showing two distributions related to measurement units. (C) Representative pairwise scatterplot (in this case end diastolic diameter vs aortic root diameter) shows two primary clusters related to measurement units, but also outliers with discordant units (red boxes).
