Table 1.

Correlations of the thromboelastometry parameters vs. the DOAC concentrations or the VKA-INR, as measured for patients on chronic anticoagulation. Peak + trough DOAC concentrations were included in this analysis. CT-EXTEM or INTEM, coagulation time determined with extrinsic or intrinsic reagents. CFT-EXTEM or INTEM, clot formation time. MCF-EXTEM or INTEM, maximal clot firmness. VKA-INR, international normalized ratio for patients on VKAs. * Based on the linear regression line (DOAC concentration vs. the thromboelastometry CT).
