Statistical Analysis
Continuous variables were presented as mean ± standard deviation (SD). Baseline patient characteristics and study outcomes were analyzed between IV and non-IV treatment arms in P. aeruginosa and MRSA groups separately. Continuous data were analyzed via independent-samples T test or Mann‐Whitney U tests for non-parametric data. Categorical data were analyzed via χ2 or Fisher’s exact tests. P-value ≤ 0.05 was considered to be significant. Statistical analysis was performed using the IBM Statistical Package for the Social Sciences (SPSS) Version 23.
