  1. N = number of patients included within each population with percentage in parentheses
  2. CI confidence interval, DVT deep vein thrombosis, ITT intention-to-treat, PE pulmonary embolism, VTE venous thromboembolism
  3. aBased on normal approximation of binomial distribution for single trial and the fixed effects approach using a weighted average (inverse variance) for pooled analyses; bMajor VTE was defined as venographic and symptomatic proximal DVT and/or non-fatal PE; cVTE-related mortality included fatal PE and deaths where VTE cannot be excluded; dIncludes any symptomatic DVT (proximal or distal) and non-fatal or fatal symptomatic PE in patients in the safety population who had undergone surgery
