Efficacy and safety of tranexamic acid in elderly patients with intertrochanteric fracture: An updated meta-analysis

Figure 7 Trial sequential analysis of tranexamic acid on risk of intertrochanteric fractures. The diversity-adjusted required information size was calculated using α = 0.05 (two sided), β = 0.20 (power 80%), and a relative risk reduction of 20%; the blue cumulative Z-curve was carried out using a random-effects model.
