- Data are presented as the number of occurrences and the percentage or as the mean and standard deviation (SD) for categorical and continuous variables, respectively. For categorical variables, the p-values are based on two-sided chi squared or Fischer’s exact tests (as appropriate), comparing the infection patients to the colonization patients. For continuous variables, the p-values are based on a t-test or Wilcoxon rank sum test. Statistically significant (p < 0.05) values are presented in bold. ICU: intensive care unit.
