Table 3 Edema, measured as the circumference of the thigh, leg and ankle according to groups and moments of evaluation. Generalized estimating equations (GEE) with normal distribution and identity link function

From: Thromboprophylaxis with unilateral pneumatic device led to less edema and blood loss compared to enoxaparin after knee arthroplasty: randomized trial
