Values are mean±SD or n (%). Statistical comparisons are indicated by common superscripts.
aPL group, patients with positive tests for antiphospholipid antibodies (aPL) without pregnancy or thrombotic morbidity; APS–RSA group, antiphospholipid syndrome patients with recurrent spontaneous abortion; NS, not significant; tRSA group, patients with recurrent spontaneous abortion without aPL but with other known thrombophilias; uRSA group, patients with recurrent spontaneous abortion without aPL or other known thrombophilias.
