Unless otherwise stated, values are expressed as n (%). aResults expressed as median (25th to 75th percentiles). bSOFA (1) means SOFA score of the first 24 hours in the hospital. AAT, appropriate antibiotic therapy; APACHE, Acute Physiology and Chronic Health Evaluation; CI, confidence interval; COPD, chronic obstructive pulmonary disease; ICU, intensive care unit; RR, relative risk; SOFA, Sequential Organ Failure Assessment.
