Correlation plots between FXI:C levels and ETP and peak height parameters measured in PRP samples. Correlation plots demonstrating the relationship between FXI:C levels and ETP measurements (A-B) and between FXI:C levels and peak height measurements (C-D) using samples without CTI (A,C) or with CTI (B,D). Thrombin generation was measured with a TF trigger of 0.5 pM in PRP samples from patients with FXI deficiency (n = 90).
