Correlation between LV EF and sphericity index. a Sphericity index moderately and negatively correlated with LV EF in the whole population (n = 68) (r = −0.45, P < 0.001). b In the subgroup analysis of patients with and without appropriate ICD therapy, sphericity index significantly correlated with LVEF in patients with appropriate ICD therapy alone (r = −0.74, P = 0.002) while there was no significant association between sphericity index and LVEF in patients without appropriate ICD therapy (r = −0.26, P = 0.06). The line for the appropriate ICD group lies significantly below the line for the no appropriate ICD group (p < 0.05)
