Fig 1. Association of IgG anti-DI-positivity with an elevated proportion of circulating oxidised β₂GPI in APS patients.

Levels of reduced β₂GPI were adjusted for the total amount of β₂GPI for each sample. Anti-DI positivity was based on a cut-off established as the 99th percentile of 200 HC. Samples from APS patients who were positive for anti-DI had a significantly lower proportion of reduced β₂GPI as compared to those from anti-DI negative patients.
