(A) Circulating DPP4 as a single prognostic biomarker for acute SARS-CoV-2 infection (WHO ordinal scale: 3–8), area under ROC (AUROC): 85.05% (95% CI [DeLong]: 79.5–90.61%; p[area = 0.5] < 0.0001; power: >99.99%). (B) Circulating DPP4 as a single prognostic biomarker for mortality among patients hospitalized and with acute SARS-CoV-2 infection. AUROC: 73.33% (95% CI: 61.98–84.68%; p[area = 0.5] < 0.0001; power: 94.80%). (C) Circulating DPP4 and age as prognostic factors of mortality among patients hospitalized and with acute SARS-CoV-2 infection in a multivariate model. AUROC: 83.45% (95% CI: 74.48–92.51%; p[area = 0.5] < 0.0001; power: 99.98%).
