Predictors of aorta-related mortality after matching
Cox regression analysis (c statistic=0.952) revealed that a higher MMP-9 level (hazard ratio [HR], 1.70; 95% CI, 1.39-2.09,P <0.001) and larger maximum aortic diameter (HR, 1.41; 95% CI, 1.11-1.80, P =0.005) (Table 3 ) were associated with higher aorta-related mortality. More details of univariate and multivariate analyses for the predictors of aorta-related mortality are shown in Table 3 .
