The distribution of LVEF values over four intervals calculated using the SH protocol and Echo. A In the rESV > 17 mL subgroup, the SH protocol and Echo were used to measure a consistent distribution of LVEF across three ranges.

The “Fraction” on the y-axis was defined as the proportion of the number of patients in the total study population
