Kinetics of specific anti-SARS-CoV-2 IgM, IgA, and IgG responses during the first 12 months after SARS-CoV-2 infection: A prospective longitudinal study
Fig 3
The differences in IgM antibody levels between different groups.
(A) The first graph compares IgM antibody levels between genders (F for female and M for male), showing the distribution of antibody levels in each group. (B) IgM antibody levels are shown as a function of age, with the 190 participants divided into two groups: under 50 years and over 50 years. Each age interval is represented by a separate box plot. (C) IgM antibody levels according to the presence or absence of comorbidities. The box plots show the distribution of antibody levels in each group. In all three graphs, the P-values are calculated using the Mann-Whitney test.
