Boxplots demonstrating changes in left ventricular (LV) and right ventricular (RV) strain (A and B) and strain rate (C and D) from beginning to end of surgery. Interquartile range (boxes), median (horizontal lines), high and low values within 1.5 interquartile range (whiskers), outliers (circles), and mean (diamonds) are shown. * P value is less than the significance level of 0.025 for two-group comparisons. HNC = hyperinsulinemic normoglycemic clamp.
