- In order to study the effect of different intensities of anti-vitamin K treatment on coagulation parameters, 23 patients with venous thromboembolism were given, after the initial treatment period, warfarin at doses giving an International Normalised Ratio of 1.3-2.0 for 4 weeks, and of 1.1-1.3 for another 4 weeks.
