Fig 2 — IL-6 levels at presentation, maximal IL-6 levels before mechanical ventilation, and receiver operating characteristic (ROC) analysis of different parameters in the evaluation and validation cohorts. Box plots showing IL-6 levels at first assessment (A and B) and maximal IL-6 levels before mechanical ventilation (C and D) in the evaluation cohort and in the validation cohort; dashed lines represents the cutoff calculated from the evaluation cohort (IL-6 level at initial assessment >35 pg/mL, maximal IL-6 level >80 pg/mL). Data are represented as means ± SDs. ROC curve of maximal follow-up levels before mechanical ventilation in the evaluation (E) and validation cohorts (F).
