Figure 1.

Time-to-first-event curves for total device-related complications, device-related complications requiring invasive intervention and lead-related complications. Shown are the cumulative event rates of the first occurrence of device-related complications (A), device-related complication requiring invasive intervention (B), and lead-related complications (C). Hazard ratios are derived from Cox regressions and indicate the relative risk (subcutaneous ICD vs. transvenous ICD) of the endpoint. P-values were not adjusted for multiple comparisons. ICD, implantable cardioverter-defibrillator; S-ICD, subcutaneous ICD; TV-ICD, transvenous ICD.
