Antibodies were detected, not their activity. Here's the assay used: https://www.cell.com/cell-reports-methods/pdf/S2667-2375(22)... Measuring antibody activity is a lot harder than measuring antibodies, just being able to assess antibody targets in a high-throughput manner is a huge and very recent step forward.
Were the antibodies detected, or was their activity detected? Because if it's just about the presence of autoantibodies, the simple explanation may be that aab quantities may not significantly differ, but their activity/activation might.
