OR: odds ratio. CI: confidence interval. IMV: invasive mechanical ventilation. SpO2/FiO2: oxygen saturation by pulse oximetry/fraction of inspired oxygen ratio. CURB-65: confusion, urea nitrogen >7 mmol/L (19 mg/dL), respiratory rate ≥30/min, systolic blood pressure <90 mmHg or diastolic blood pressure ≤60 mmHg, and age ≥65 years. CORB: confusion (new onset or deterioration of preexisting condition), oxygen saturation ≤90%, respiratory rate ≥30/min, and systolic blood pressure <90 mmHg or diastolic blood pressure ≤60 mmHg. Hosmer–Lemeshow test: 0,598; 0,238; 0,498; 0,247; 0,328. |
