  1. 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 a 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. RACHS: risk adjusted congenital heart surgery, ICU: intensive care unit; DHCA: deep hypothermic cardiac arrest; RBC: red blood cells; CPB: cardiopulmonary bypass.
