Abbreviations: ALIF and TLIF anterior and transforaminal lumbar interbody fusion, RBC red blood cell packs, FFP fresh frozen plasma units, CATS-blood continuous autotransfusion system blood. Statistical analyses regarding p-values were performed between the three columns/groups, i.e. early complications (2), late complications (3) and no complications (4); see superscripted numbers (significance at p < 0.05 or at p < 0.01)
