Prognostic value of a combined approach of IL-6, IL-8, PCT and baseline qSOFA. A AUC for baseline qSOFA (Day 0) with IL-6 (Day 0). B AUC for baseline qSOFA (Day 0) with IL-6 (Day 1). C AUC for baseline qSOFA (Day 1) with IL-6 (Day 1). D AUC for baseline qSOFA (Day 0) with PCT (Day 0). E AUC for baseline qSOFA (Day 0) with PCT (Day 1). F AUC for baseline qSOFA (Day 1) with PCT (Day 1). G AUC for baseline qSOFA (Day 0) with IL-8 (Day 0). H AUC for baseline qSOFA (Day 0) with IL-8 (Day 1). I AUC for baseline qSOFA (Day 1) with IL-8 (Day 1). Comparison of AUC revealed that the combination model using additional serum IL-6 concentration on Days 0 and 1 had a significantly higher AUC than the baseline model that uses only the qSOFA score. AUC = area under the curve, qSOFA = quick sequential organ failure assessment, IL = interleukin, PCT = procalcitonin
