No.	Prevention	Inducibility	Multivariable hazard ratio (95% confidence interval), P value	Reference
408	P	40%	5.88 (2.0–16.7), o.001	Brugada [364]
308	P	41%	0.89 (0.3–2.6),.84	Priori [49]
638	P/S	62%	N/A, 0.48	Probst [247]
245	P	39%	Not tested on multivariable analysis, but an analysis based on C–statistics demonstrated that results of electrophysiologic studies in combination with other risk factors provided additional value for risk stratification	Delise [262]
