Figure 3. Receiver operating characteristic (ROC) curve of maximum ferritin in patients with or without viral DNAemia.

Figure 3.

ROC was performed for plasma ferritin in 30 patients with severe sepsis and viral DNAemia and 45 patients with severe sepsis without DNAemia. Area under the curve is 0.7007 (95%CI: 0.576 – 0.8255; p<0.01). Identified are the points which correspond to optimal cutoffs identified by Youden J statistic (ferritin > 930 ng/mL) and likelihood ratio (ferritin > 2755 ng/mL).
