Answer

Carruthers et al reported that patients with polymyositis are at increased risk for venous thromboembolism (VTE), with hazard ratios of 7.0 for VTE, 6.16 for deep venous thrombosis, and 7.23 for pulmonary embolism. Overall, the highest calculated incidence rate ratios were observed in the first year after diagnosis of polymyositis. [14]
