It is true that the absence of statistical evidence does not imply that this evidence does not exist, but it also depends on the size of the sample used. It is necessary to consider the clinical importance of the investigated fact. Although our study groups are wide enough to carry out a correct statistical analysis, we agree that improving the size of the sample would improve the power of the test; and to get that, it is necessary to enlarge the study in the future. Every recurrence is an outstanding clinical event; it represents the failure of the surgical technique used and the patient suffers from it. However, the conclusions of our scientific work are supported in the statistical study and not in opinions about seemingly different results.
