IgM-autoantibody levels and the presence or the absence of renal involvement or ASCVD events. Healthy n=28, anti-PC, anti-MDA patients with renal disease n=27, patients without renal disease n=93, patients with ASCVD event n=25, patients without ASCVD event n=95. For anti-β2-GPI, -CL, and anti-dsDNA: patients with renal disease n=25, patients without renal disease n=70, patients with ASCVD event n=23, patients without ASCVD n=78. In some cases the amount of sample was not adequate for all tests. p-Values were determined with two-sided Mann–Whitney non-parametric testing, with significant values indicated.
