Figure 2. Changes in Left Ventricular Ejection Fraction (LVEF) According to the Presence of Stress-Induced Ischemia.
The delta LVEF (difference in reduction of LVEF) is calculated as 100 × [(LVEF at 10 years − LVEF at baseline)/LVEF at baseline]. The vertical line in the middle of each box indicates the median; left and right borders of the box, the interquartile ranges; whiskers, the maximum and minimum values excluding the outliers; and data points beyond the whiskers, outliers.
