NOTE. Data are no. (%) or mean [Q1-Q3]. Statistical analysis was done comparing the two groups (Abscess vs no abscess). ASA, American society of anesthesia; ATB, antibiotics; COPD, chronic obstructive pulmonary disease; GCS, Glasgow coma scale; ICU, intensive care unit; LA, lung abscess; OR, odds ratio; SAPSII, simplified acute physiologic score
