<p>Dear Editor,</p><p>The study is well designed and there are few alterations to make it available for publication. It is a simple paper to read and comprehend. In my personal view, it fails in discussion. If the authors are able to improve the discussion and make it more articulated with the introduction and the objectives of the study, my recomendation is to publish the paper.</p><p> </p><p>My kind regards,</p><p>Alexandra Gomes</p>
