Values are presented as mean ± SD. ROTEM: rotational thromboelastometry, INTEM: intrinsically activated test of ROTEM assays (activation with phospholipid and ellagic acid), EXTEM: extrinsically activated tests of ROTEM assays (activation with tissue factor), FIBTEM: extrinsically activated tests of ROTEM assays (activation with cytochalasin D followed by tissue factor), CT: clotting time, CFT: clot formation time, α: alpha-angle, MCF: maximum clot firmness.
