Receiver-operator curves for noncontrast variables. Plots for combined model with native T1, Ɛcc, and εls with modest areas under the curve (AUC) for prediction of presence/absence of LGE for all CMRs (a) and in the subset with normal left ventricular ejection fraction (LVEF) (c). The best performance was for predicting high grade [global severity score (GSS) ≥ 3] vs low grade (GSS ≤ 2) for all CMRs (b)
