  1. For all secondary judgment criteria, the parameter estimates of the regression models were estimated by bootstrapping. The models were weighted based on the final propensity score. p-values are for comparison between carbapenem group and non carbapenem group. Threshold for statistical significance: p = 0.05
  2. Results are presented as proportion (percentage) for categorical variables and median [interquartile range] for continuous variables
