Fig. 3From: Plasma SARS-CoV-2 nucleocapsid antigen levels are associated with progression to severe disease in hospitalized COVID-19a Plasma SARS-CoV-2 N-antigen concentration on D0 by change in clinical status on the World Health Organization ordinal scale. b Plasma viral N-antigen concentration on D0 in patients who were not initially admitted to the ICU at the time of study recruitment, stratified by ICU admission during hospitalization. c Plasma SARS-CoV-2 N-antigen concentration on D0 stratified by mechanical ventilation at 28 days. d Plasma SARS-CoV-2 N-Antigen concentration on D0 stratified by death at 28 days. Plasma N-antigen concentration is presented on log10 scale. P values represent the results of the Wilcoxon rank-sum testBack to article page
