Impact of VAP on hospital LoS, duration of MV, and all-cause mortality in study population. a: All subjects; b: subjects admitted to the medical ICUs; c: subjects admitted to the surgical ICU. Geometric mean +/− 95% confidence interval is shown. Significance, calculated by two-tailed unpaired t-test (hospital LoS, MV duration) or with Fisher’s exact test (mortality) is indicated when p-value is < 0.05. *1 patient excluded since MV start date was not recorded
