Table 2.
Regression analysis was performed to investigate the risk factors of ICU mortality and hospital mortality for cardiogenic shock patients.

Data displayed as HR [95%CI] with P-value using multivariate logistic regression using stepwise backward variable selection. BMI, Body Mass Index; APACH-IV, acute physiology and chronic health evaluation score IV; LOS, length of stay; HR, hazard ratio; 95%CI, 95% confidence interval.
