Baseline Characteristics of Study Patients with IAB Based on Bacterial Species.

Data are reported as mean ±S.D. or number (%). *Values were reported as median (interquartile range). 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.
