Tranexamic acid in pertrochanteric fractures: a retrospective analysis of perioperative outcomes after fixation with a proximal femoral nail

Table 3 Intraoperative parameters, surgical approach and knife-to-skin time, mean values, standard deviations (mean ± SD) as well as 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
