Figure 6.

Radar charts showing the relative importance of input features, as determined using the permutation approach; (a) 1-year recurrence model; (b) 1-month recurrence model. Values denote the reduction in mean AUC after shuffling the values of the given feature. EF: left ventricular ejection fraction; VT: ventricular tachycardia; TAPSE: tricuspid annular plane systolic excursion; ICD: implanted cardioverter defibrillator; LVESD: left ventricular end systolic diameter; HD: hemodynamic; MR: mitral regurgitation.
