Fig 2.
Comparison of receiver operating characteristic (ROC) curves for prediction of ICU mortality by Sequential Organ Failure Assessment (SOFA) using Glasgow Coma Scale (GCS), Richmond Agitation and Sedation Scale (RASS) and Full Outline of UnResponsiveness (FOUR) neurologic assessment substitutions in the total cohort (A), subset undergoing mechanical ventilation (B) and septic subset (C). Comparisons between the absolute and differences of AUC were considered significant for p<0.05. AUC = area under the curve.

Adjusted and unadjusted Cox regression model for ICU mortality.
The effects of traditional and modified SOFA upon survival are constant over time and did not vary when each one was adjusted for age, gender and BMI (body mass index).
