Kinetics of anti-SARS-CoV-2 IgG-N and IgG-S1 in 40 patients with type 2 diabetes and 40 patients without diabetes Antibody levels were log2-transformed. Blue lines represent the threshold value for positive. Comparisons of antibody titers in the same time period were performed using the Mann–Whitney U-test. *P < 0.05. Abbreviations: DM, diabetes mellitus; IgG-N, immunoglobulin G specific for nucleocapsid protein; IgG-S1, immunoglobulin G specific for the S1 subunit of the spike protein; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2
