From: Effectiveness of tranexamic acid in reducing blood loss in spinal surgery: a meta-analysis
The average amount of blood loss was significantly less in the TXA group, either in subgroup of anterior-posterior approach with high TXA dose or in subgroup of posterior approach with low TXA dose (weighted mean difference, -550.81 ml [95% CI, -873.51 to -228.11 ml]; p = 0.0008; weighted mean difference, -93.18 ml [95% CI, -134.84 to -51.52 ml]; p < 0.0001 respectively;). TXA = tranexamic acid, SD = standard deviation, IV = inverse variance, and df = degrees of freedom.
