Definition of abbreviations: OR odds ratio, CI confidence interval
^aThe ORs were adjusted for parameters of the A-DROP or risk score for non-elderly patients
^bAge was excluded from this table because all patients were <65 years. The c statistic for the model is 0.73273
^cThe existence of a clinical sign of dehydration or blood urea nitrogen level ≥210 mg/L
^dSpO₂ ≤ 90 % or PaO₂ ≤ 60 mmHg
^eSystolic blood pressure ≤90 mmHg
^fThe c statistic for the model is 0.86673
^gAny malignancy including metastatic solid tumour
^hThe reference group is 18–39 years
