^*No significant interaction of risk category and treatment (p=0.35): ERV vs. No/Late Revascularization Relative Risk=0.80 (95% CI 0.64 to 0.99); Odds Ratio=0.62 (95% CI 0.45 to 0.85)

Timing of revascularization was not available for 47 patients

ERV=Early Revascularization (≤18 hours following shock diagnosis
