TOPLINE:
Patients with rheumatoid arthritis (RA) had a 46% higher risk for venous thromboembolism (VTE) than matched control individuals, with an elevated risk persisting across all age groups, BMI categories, and disease durations.
METHODOLOGY:
Researchers conducted a matched cohort study to assess the risk for VTE in individuals with RA and to examine how the risk varied according to demographic and clinical factors.
They included 23,410 patients with RA (mean age, 59.0 years; 71.1% women; mean BMI, 27.1) having no history of VTE and 93,640 matched control individuals who were registered with a UK general practice between 1999 and 2018.
The primary outcome was the diagnosis of VTE, including deep venous thrombosis and pulmonary embolism as composite outcomes, using diagnosti
