Continuous variables are depicted as median with interquartile range (25–75) in parenthesis and categorical outcomes as absolute n with% frequency in parenthesis. Charlson comorbidity index, APACHE II and SOFA scores are presented in this table as continuous variables. CCI, Charlson comorbidity index; CT, computed tomography; CTPA, computed tomography pulmonary angiography; PPE, parapneumoic effusion; CTD, connective tissue disease; APACHE II, acute physiology and chronic health evaluation; SOFA, sequential organ failure assessment.
