aCL categories were defined using aCL-IgG test results at entry: normal < 23 GPL; Low 23.0–29.9 GPL; intermediate 30–49.9 GPL; high ≥ 50 GPL.
**
The percentage (%) of individuals in each aCL category was: 23.9, 25.4, 23.9, and 26.9 for individuals without thrombosis and 20.0, 25.0, 20.0, and 35.0 for individuals with thrombosis.
