  2. aThe counts of Acinetobacter VAP among the three categories of control groups and the category of observation groups among studies after excluding those with length of stay < 7 days differed significantly (p < 0.001; Fisher’s exact test)
  3. bThe counts of Acinetobacter VAP among the three categories of intervention groups and the category of observation groups among studies after excluding those with length of stay < 7 days differed significantly (p = 0.038; Fisher’s exact test)
  4. cThe counts of Pseudomonas VAP among the three categories of control groups and the category of observation groups among studies after excluding those with length of stay < 7 days differed significantly (p < 0.001; Fisher’s exact test)
  5. dThe counts of Pseudomonas VAP among the three categories of intervention groups and the category of observation groups among studies after excluding those with length of stay < 7 days differed marginally (p = 0.05; Fisher’s exact test)
