Fig. 4 — Sensitivity analysis of the incremental cost-utility ratio (ICUR). Notes: QALYs: Quality adjusted life years. The variation in QALYs was the 95% Confidence Interval upper (0.106704) and lower (0.040027) value of the mean utility (0.073366) in the topical TXA group. USPPP: $US Purchasing Power Parities are the rates of currency conversion that equalise the purchasing power of different currencies by eliminating the differences in price levels between countries. The variation in topical Tranexamic Acid (TXA) cost ranged from zero (control cost) and 25.8 USPPP, which is 100% higher than the unit cost of TXA
