Table 4 Multivariable logistic regression analysis of factors associated with 28-day mortality

From: Double carbapenem as a rescue strategy for the treatment of severe carbapenemase-producing Klebsiella pneumoniae infections: a two-center, matched case–control study

Variable p value OR (95% CI)
SAPS II score <0.01 1.08 (1.04–1.23)
SOFA score ≤0.01 1.36 (1.33–1.63)
Double carbapenem treatment 0.02 0.33 (0.13–0.87)
  1. We included all variables in the multivariable logistic regression if they reached p ≤ 0.1 on univariate analysis. A stepwise selection procedure was used to select variables for inclusion in the final model
  2. ROC curve analysis was used to assess the goodness of the final logistic regression model (AUC ± SE = 0.85 ± 0.034 with 95% CI 0.78–0.91; chi-square statistics p < 0.001)
  3. AUC area under the curve, OR odds ratio, ROC receiver operating characteristic, SAPS Simplified Acute Physiology Score, SOFA Sequential Organ Failure Assessment, SE standard error
