Figure 1. IgM and IgG response in RP patients compared with non-RP patients. (a) IgM antibody response profile against 20 SARS-CoV-2 proteins in 113 non-RP patients and 21 RP patients. (b) IgG antibody response profile against 20 SARS-CoV-2 proteins in 113 non-RP patients and 21 RP patients.Each square in heatmap indicates the IgM or IgG antibody response against the protein (column) in the serum (row). The proteins and serum samples were arranged with clustering.
