Figure 2. Adjusted Kaplan-Meier survival curves for mortality according to early AVR within 2 years of index echocardiography. Comparison of mortality between the early AVR group versus the medical observation group after multivariable-adjusted Cox proportional regression analysis. (A) All-cause death. (B) Cardiovascular death.

AVR = aortic valve replacement; CI = confidence interval; HR = hazard ratio.
