Number of patients with bacterial, viral, or any (bacterial and/or viral) potential pathogens detected by MTB and BPFA

Bacteria MTB BPFA Effect Measure p-value*
Any bacteria, patient No. (%) 182 (66.4%) 207 (75.5%) OR (95% CI) = 2.09 (1.24,3.59) 0.003
Number of bacterial species per patient
Mean (SD) 0.92 (0.82) 1.35 (1.19) Diff (95% CI=0.43(0.30,0.56) <0.001
Median (IQR) 1 (0,1) 1 (1,2) NA <0.001
Virus
Any virus, patient No.(%) 111 (40.5%) 167 (60.9%) OR (95%CI)=9.00(4.12,23.30) <0.001

MTB = Multi-test bundle; BPFA = BioFire® Pneumonia FilmArray®

p-value was based on McNemar test for odds ratio, paired t-test for mean difference, and Wilcoxon signed rank test for distribution
