A case was defined as a subject who developed a (by protocol defined) ICUacquired pneumonia. Continuous nonparametric data were analyzed using a Wilcoxon signed rank sum- or Kruskal-Wallis test; categorical data were analyzed using a Fisher exact test; continuous parametric data were analyzed using a Student t test; a P value < 0.05 was considered statistically significant. 5
