Mixed-effects logistic regression for in-hospital mortality
The overall estimated in-hospital mortality was approximately 4.3% (n= 1,087), being significantly higher for the Hispanic group after pairwise comparisons (4.1% vs. 4.2% vs. 6.2% vs. 4.1%; p<.001). However, the adjusted multivariable model showed that race was not an independent factor associated with in-hospital mortality (Table 3 ). Instead, the association with cerebrovascular disease (OR 2.3, CI 95% 1.6 – 3.4), a non-elective admission (OR 2.2, CI 95% 1.5 – 3.1), peripheral artery disease (OR 1.6, CI 95% 1.2 – 2.2), and chronic kidney disease (1.45 (1.01 – 2.07), were all highly associated with in-hospital mortality.
