Fig. 4From: Prognostic value of cardiovascular magnetic resonance T1 mapping and extracellular volume fraction in nonischemic dilated cardiomyopathyCumulative 2-year arrhythmia-related event-free survival rate depending on CMR parameters. A Native T1 Z-score: < 4.2 vs. ≥ 4.2; based on the optimal cutoff determined by the Youden index. B Late gadolinium enhancement (LGE): present vs. absent. C Extracellular volume (ECV): < 30.5% vs. ≥ 30.5%; based on the optimal cutoff determined by the Youden index. D Left ventricular ejection fraction (LVEF): < 34.0% vs. ≥ 34.0%; based on the optimal cutoff determined by the Youden indexBack to article page
