Thank you for the opportunity to respond this Letter to the Editor.
We would like to inform that all usual procedures were taken to avoid errors during the bioimpedance analysis (BIA). All tests were done early morning, at the same time with constant temperature to keep the testing environment and methodology adequacy. The patients were carefully advised to avoid physical activities, alcohol, food, and medications before the test that was performed with 12-h-fasting and empty bladder.
As all these procedures are usual in clinical practice, they were not included due to the limited words of our article published as Brief Communication, but they are really very important to perform and evaluate the research.
To the best of our knowledge, BIA can be a feasible alternative tool to assess body composition because of its simplicity and noninvasiveness and had been validated with dual-energy X-ray absorptiometry (DXA) .
Furthermore, the same patients were evaluated with the same device and in the same environmental conditions before and after treatment, which certainly helps to minimize small differences and validate our results.
