The amount of blood loss per patient was significantly less in the tranexamic acid group compared with the placebo group (weighted mean difference, −504.90 mL [95% CI, −620.89 to

−388.92 mL]; p < 0.00001).

The number of blood transfusions per patient was significantly less in the tranexamic acid group compared with the placebo group (weighted mean difference, −1.43 units [95% CI, −1.69 to −1.17

units]; p < 0.00001).



The rate of patients requiring transfusion was significantly less in the tranexamic acid group compared with the placebo group (OR, 0.16 [95% CI, 0.10 to 0.25]; p < 0.00001).



The rate of deep-vein thrombosis was not affected for the tranexamic acid group as compared with the placebo group (OR, 0.75 [95% CI, 0.34 to 1.67]; p = 0.48).



The rate of pulmonary embolism was not affected for the tranexamic acid group as compared with the placebo group (OR, 0.65 [95% CI, 0.18 to 2.33]; p = 0.50).



Prothrombin time was not affected for the tranexamic acid group as compared with the placebo group (weighted mean difference, −0.04 second [95% CI, −0.33 to 0.24 second]; p = 0.77).



Activated partial thromboplastin time was not affected for the tranexamic acid group as compared with the placebo group (weighted mean difference, 0.37 second [95% CI, −0.56 to 1.29

seconds]; p = 0.44).
