Clinical Features at the Onset of IAB in Study Patients with IAB Based on Bacterial Species.

Data are reported as mean ±S.D. or number (%). Nonparametric Chi-Square test and Kruskal-Wallis test were used for the six most common pathogens of IAB to compare categorical and continuous variables, respectively, and p values are depicted in the table. The Chi-Square test/Fisher exact test and Mann-Whitney U test were used for categorical and continuous variables, respectively, to identify the significant difference between patients harboring the individual pathogen versus patients not harboring this pathogen. APACHE, Acute Physiology and Chronic Health Evaluation; BUN, blood urea nitrogen; ICU, intensive care unit; MRSA, methicillin-resistant Staphylococcus aureus. ap<0.05, IAB due to P. aeruginosa vs. non-P. aeruginosa; bp<0.05, IAB due to E. meningoseptica vs. non-E. meningoseptica; cp<0.05, IAB due to A. baumannii vs. non-A. baumannii.
