Table 5 Postoperative parameters, mean values, standard deviations (mean ± SD) and minimum and maximum values (range). The values are presented both overall across groups as well as separately for patients treated with and without tranexamic acid (TXA) and for the two centres. The p-value (P) is with respect to the differences between the two patient groups (nonTXA and TXA) and between the two centres (location) is listed accordingly
