Comprehensive analysis of viremia as a prognostic marker of mortality in patients hospitalized for severe COVID-19. ROC curve-analysis for mortality prediction with Ct values in serum of all patients, according to Roche (A) and Thermo Fisher Scientific [TFS] (B) techniques. Proportion of deceased patients according to the presence (positive) of absence (negative) of relevant viremia determined by Roche (C) and TFS (D) techniques. Survival analysis with Kaplan–Meier estimator of patients hospitalized for COVID-19 who presented (dotted lines) and patients who did not present (solid lines) relevant viremia according to Roche (E) and TFS (F) techniques.
