Association between viremia and main sociodemographic and clinical characteristics of patients hospitalized with severe COVID-19. Correlation between viremia levels (Ct value) and (A) age (years) and (B) Charlson comorbidity index (score). Distribution of viremia levels according to qSOFA index (C), and CURB65 scale (D) scores. All Ct data shown here were obtained by rRT-PCR in serum with Thermo Fisher Scientific (TFS) technique. In (A) and (B) data are shown as dot plots of the corresponding values and the fitted linear prediction (black line) obtained with the option lfit of the command twoway of Stata. Correlation coefficients and significance levels were estimated with the Pearson’s test. In (C) and (D) data are shown as box-plot representing the interquartile range (p75 upper edge, p25 lower edge, p50 midline in the box), p95 (line above the box), and p5 (line below the box). Significance level was determined with the Kruskal Wallis test.
