Men exhibited higher rates of ocular, vascular and neurological involvement, while women had more joint involvement. HLA-B51 was associated with joint and ocular involvement and pathergy positivity. Early-onset disease (onset &amp;lt; 16\u2005years) was observed in 11% (n = 448\/4007) of patients and was associated with increased rates of systemic involvement. Joint involvement (n = 1553\/4007, 39%) mostly appeared as arthralgia or arthritis. Gastrointestinal involvement (n = 115\/4007, 2.9%) was associated with diabetes mellitus. Pathergy positivity was observed in 21% (n = 823\/4007) of patients and was associated with early disease onset and smoking. Multivariable analyses showed that male sex and early disease onset were associated with ocular and neurological involvement, whereas vascular involvement was associated with male sex, early onset and
