Fig. 3: IgG and IgM levels in the acute and convalescent phases in patients infected with SARS-CoV-2.
From: Clinical and immunological assessment of asymptomatic SARS-CoV-2 infections
a, The comparison of virus-specific antibody levels in asymptomatic patients (n = 37) and symptomatic patients (n = 37) with acute infections. b, IgG levels in patients with convalescent-phase COVID-19 who were discharged from the hospital. c, Dynamic changes in virus-specific IgG levels in the acute and convalescent phases. d, Dynamic changes in neutralizing serum antibodies in the acute and convalescent phases. Results are expressed as the average of two independent experiments. e, IgG-positive proportions of patients with COVID-19 in the acute and convalescent phases. The box plots in a and b show the medians (middle line) and first and third quartiles (boxes), and the whiskers show 1.5× the IQR above and below the box. Unpaired, two-sided Mann–Whitney U test P values are depicted in the plots, and the significant P value cutoff was set at 0.05.
