  1. OR odds ratio, 95%CI 95% confidence interval, ICC intra-class correlation, UTI urinary tract infection, cUTI complicated urinary tract, and MDR-GNB Multidrug-resistant Gram-negative bacteria
  2. aThe ICC (range 0 to 1) expresses the magnitude of clustering. A high ICC (generally higher than 0.1) means that individuals within centers are more similar than between centers
