  1. Discrete variables used χ2 test or Fisher exact test
  2. The incidence of Grade 2 and 3 seroma or late seroma in Grade 2 and 3 was significant higher in the conventional suture group compared with that in the quilting group (p = 0.032 and p = 0.005 respectively). The incidence of Grade 1 seroma was significantly higher in quilting group compared with that in the conventional group (p = 0.008).
