Comparison of Bacteria Between Conventional Cultivation Methods and 16S rDNA Sequencing Analysis in the Bacterial Infection Group

Risk factors (Positive/Negative)**	The percentage of clones of MRSA phylotype (%)
	Positive	Negative	P-value
Use of Glucocorticoid**/Immunosuppressant (6/36)	40.2 ± 41.4	19.0 ± 28.3	0.305
Histories/Risks of aspiration (23/19)	18.7 ± 33.2	25.2 ± 29.2	0.422
Antibiotic therapy in the preceding 90 days (12/30)	30.1 ± 40.7	17.5 ± 25.7	0.391
History of pathogens detection in the preceding 90 days* (9/30)	38.2 ± 35.1	15.4 ± 28.9	0.105

*Unknown data in three cases, **“Positive” and “Negative” indicate the number of patients with or without each risk factor, respectively.
