  Figure 2. Time‐to‐event data for venous thromboembolism in Japanese patients with major trauma. Black bar indicates median value. The median time from admission to venous thromboembolism diagnosis was 10 days.

  Figure 3. Changes in D‐dimer levels from time of injury to day 14 among Japanese patients with major trauma. Patients are grouped according to the presence of venous thromboembolism ((+) VTE), without VTE by computed tomography (CT) imaging ((−) VTE), and without CT examination ((−) CT). *P < 0.05, significant difference between (+) VTE and (−) VTE groups. †P < 0.05, †††P < 0.001, significant difference between (−) VTE and (−) CT image groups.
