Distribution of antiphospholipid antibodies
The distribution of all criterial or non-criterial aPLs among different
patient groups was shown in Figure 3. Levels of aPLs were calculated
with (log(test value + 2)U/ml). The results of primary or secondary APS
were compared to other groups. No significant difference was observed
between primary and secondary APS, except for aCL IgM (p = 0.029) and
aβ2GpI IgA (p = 0.043). Compared to HC, levels of IgG and IgA were
significantly higher for four aPLs in both PAPS and SAPS group. However,
IgM results varied for different aPLs.
