PP = Primary prevention
* Primary prevention subgroup
† Subgroup of patients with LVEF< = 35%/all patients
§ Indirect estimate based on the 74% of PP in the baseline cohort (3543 patients) and the claim of no significant baseline differences between patients with and without follow-up
# Not included in the meta-analysis, given a large overlap with Yung et al
& Appropriate shock considered, but hazard ratio from a Cox proportional hazards model not provided.
