Primary Outcome = PTS incidence 24 months after DVT diagnosis
In group 1 (stop-ECS), 51 patients got sick from post thrombotic syndrome, while in group 2 (continue-ECS) it were 34 patients. The risk for PTS in the stop-ECS group is 60% higher compared to the continue-ECS group.
To prevent one case of PTS by continuing ECS therapy for 24 months, the number of patients needed to treat is 14.
The continue-ECS group showed a high compliance rate, as 85% of this group wore the ECS for 6-7 days per week.
