  1. All biologically plausible variables with a p-value < 0.05 in the univariable analysis were considered for inclusion in the logistic regression model in the multivariable analysis. A stepwise selection process was utilized. We found that only cerebrovascular accident, recent surgery, extensive drug resistance, APACHE II score, and appropriate therapy were statistically significant factors for 14-day mortality
