Table 3 Continuous outcome comparisons

From: Conventional suture with prolonged timing of drainage is as good as quilting suture in preventing seroma formation at pectoral area after mastectomy

  

Quilting suture (group 2) n=116

Conventional suture (group 2) n=139

Conventional suture (group 3) n=133

  1. Continuous variables used one-way ANOVA test. Outcome comparisons among the three groups. Quilting suture was significantly associated with less volume of drainage compared with that of conventional suture groups 2 and 3 (p < 0.001)
