ICU, intensive care unit; IQR, interquartile range; MV, mechanical ventilation; SIRS, systemic inflammatory response syndrome; SOFA, sequential organ failure assessment.

Note: SOFA+, patients with SOFA variation ≥2 over their baseline clinical score. SIRS+, patients with at least 2 of the following signs of SIRS: temperature > 38 °C or <36° C, heart rate > 90 beats per minute, respiratory rate > 20 breaths per minute or PaCO2 < 32 mmHg, abnormal white blood cell count (>12,000/μL or <4000/μL or >10% immature forms).
