Scatterplots. Comparing Quantra and ROTEM sigma measurements as well as between Quantra/ROTEM sigma and platelet count for sample 1 and 2. Black filled circles represent measurements of sample 1, open circles represent measurements of sample 2. Abbreviations: CS, Clot Stiffness of the Quantra in hectopascal (hPa); FCS, Fibrinogen Contribution to Clot Stiffness of the Quantra (hPa); CT, Clot Time in seconds (sec) of the Quantra; CTH, Heparinase Clot Time (sec) of the Quantra; PCS, Platelet Contribution to Clot Stiffness (hPa) calculated by subtracting FCS from CS of the Quantra. EXTEM A10, clot stiffness of the ROTEM after 10 min running time (hPa); FIBTEM A10, fibrinogen contribution to clot stiffness of the ROTEM after 10 min running time (hPa); INTEM CT, Clot time of intrinsic pathway of the ROTEM (sec); HEPTEM CT, Clot time of the intrinsic pathway after neutralization of heparin of the ROTEM (sec); EXTEM A10 – FIBTEM A10, Platelet contribution to clot stiffness of the ROTEM after 10 min running time (hPa); Platelets, platelet count (109/L).
