Results: In the treatment group the median activities of prothrombin were 37.3%, F VII were 62.4%, F IX were 29.5%, and F X were 34.9%, while in the control group the median activities of prothrombin were 33.5%, F VII were 47.3%, F IX were 23.7%, and F X were 29.0%. The difference of the activities of vitamin K dependent factors between treatment group and control group was statistically significant.
