Recalibrated SOFA-derived score

PaO₂/FiO₂ (mmHg) Worst value in the first 24 h. PaO₂ in mmHg divided by FiO₂ as a fraction (50 % → 0.5).

Glasgow Coma Scale, total 3 to 15. Lowest value in the first 24 h.

Mean arterial pressure (mmHg) Enter the most physiologically deviant value of the first 24 h, low or high. This variable scores in both directions: readings above 138.5 mmHg also add points.

Platelets (×10⁹/L) Same number as ×10³/µL.

Creatinine (mg/dL) Highest value in the first 24 h. Urine output is not used.

Total bilirubin (mg/dL) Highest value in the first 24 h.
