Fig. 3From: IgG antibody titers against SARS-CoV-2 nucleocapsid protein correlate with the severity of COVID-19 patientsDifference in serum titer for the different severity. Group 1: SARS-CoV-2-N IgG antibody titer for 24 asymptomatic and mild cases; Group 2: SARS-CoV-2-N IgG antibody titer for 48 moderate cases; Group 3: SARS-CoV-2-N IgG antibody titer for 16 severe and critical cases. The significance of the difference was indicated using ‘* ‘(p < 0.05) and ‘*** ‘(p = 0.000)Back to article page
