RBD-IgG, RBD-Ab and neutralizing antibody titre of COVID-19 discharged patients’ convalescent sera. a-c RBD-IgG (COI) (a), RBD-Ab (COI) (b) and neutralizing antibody titre (c) of patients’ sera with different clinical types. Cutoff index (COI) value = the sample detection value/cutoff value. Each set of data was represented by the median (interquartile range). Each black dot represented the antibody detection value of each serum sample. d Correlation analysis among the RBD-IgG, RBD-Ab, neutralizing antibody titre, the disease severity and age groups. The figures showed the scatter plots, Spearman correlation coefficients and the red lines were trend lines
