Bland Altman analysis. Plots for comparison of corresponding measurements of the Quantra and ROTEM sigma for sample 1 and 2 (EXTEM A10 and CS; FIBTEM A10 and FCS, INTEM CT and CT, HEPTEM CT and CTH; EXTEM A10-FIBTEM A10 and PCS). Data pairs of sample 1 are presented as solid circles and data pairs of sample 2 are presented as open circles. Y-axis represents the bias (difference of the methods) and X-axis the mean of both measurements. The mean bias (mean difference of the methods) is shown as solid line and the 95% limits of agreement is shown by the dashed lines. 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)
