Kaplan-Meier curves of recurrent DVT during follow-up. Event-free survival in patients with recurrent DVT following discontinuation of anticoagulation with regard to permeability coefficient, K_s (log-rank P < .001), lag phase (log-rank P < .001), difference between maximum and minimum absorbance in the turbidimetric clotting assay, ΔAbs (log-rank P = .03), maximum D-dimer levels in the lysis assay, D-D_max (log-rank P = .01), maximum rate of D-dimer release from fibrin clots, D-D_rate (log-rank P < .001), CLT (log-rank P < .001), CRP (log-rank P = .01), D-dimer (log-rank P < .0001), peak thrombin (log-rank P < .0001), ETP (log-rank P < .001), and time to thrombin peak (log-rank P = .01). HRs (with 95% CIs) and P values are presented.
