  1. 3-point scale (1: deficient, 2: adequate, 3: ideal); A) insertion and exit points were on the same plane; B) distance between the incision and insertion and exit points were similar; C) the length of the suture was similar to the distance between each one; D) knot firmness did not loosen with light/moderate manipulation; E) adequate suture tension
