Fig 4 — Cutoffs and predictive values of maximal IL-6 and CRP level values in the combined cohort. Box plots depicting the maximal values of IL-6 and CRP levels in the overall cohort (A and B); dashed line represents the validated cutoff; dotted line represents the calculated improved cutoff from all patients (applicable only for IL-6). PPV and NPV as a function of different cutoffs are shown for IL-6 (C) and CRP (D) level values (dotted line represents cutoff for perfect NPV; dashed line represents cutoff for perfect PPV).
