Data are expressed as median (25th–75th percentile); CWA, clot waveform analysis; APTT, activated partial thromboplastin time; sTF/FIXa, small amount of tissue factor-induced FIX activation assay; 2nd DP, second derivative peak; 1st DP, first derivative peak; FF, fibrin formation; *, p < 0.05; **, p < 0.01; ***, p < 0.001 in comparison to healthy volunteers; ###, p < 0.001 in comparison with patients with platelet counts of <8.0 × 104/L.
