Of note, they do not explain the differences in type IV collagen levels as hypothesized by Chen et al. The observed frequencies of comorbidities are as it follows: 76.32% of patients with significant fibrosis had diabetes, 76.32% dyslipidemia, 50% hypertension and 76.31% obesity. The group of NAFLD patients with advanced fibrosis had 72.22%, 77.78%, 55.56% and 38.89% of those complications respectively. Therefore, the only statistically different feature was obesity, which was interestingly more frequent in the group with less fibrosis.</p></li><li class="elsevierStyleListItem" id="lsti0015"><span class="elsevierStyleLabel">3</span><p id="par0025" class="elsevierStylePara elsevierViewall">At last, we appreciate the sagacious remark about the size of each group of fibrosis classification. Necessarily, the number of patients with significant fibrosis (F2–F4) has to be greater than the number of patients with advanced fibrosis (F3–F4) because one group encompasses the other. We had 38 patients with significant fibrosis; 20 were classified as F2 and 18 as advanced fibrosis. To eliminate the doubt raised by Chen et al., we calculated the mean type IV collagen level of each group, 26.81 for the F2 and 35.91 for the F3–F4, with a two-tailed T-test of 0.02.</p></li></ul></p><p id="par0030" class="elsevierStylePara elsevierViewall">We consider the researchers’ notes are relevant. Still, we believe that they do not detract from the data already revised by the committee of the editorial board of Annals of Hepatology and published in this renowned journal. Thank you for the opportunity to clarify possible doubts about our paper.</p></span>" "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2020-12-21" ] "idiomaDefecto" => "en" "url" => "/16652681/000000220000000C/v3_202107300613/S1665268121000181/v3_202107300613/en/main.assets" "Apartado" => array:4 [ "identificador" => "82754" "tipo" => "SECCION" "en" => array:2 [ "titulo" => "Letters to the editor" "idiomaDefecto" => true ] "idiomaDefecto" => "en" ] "PDF" => "https://static.elsevier.es/multimedia/16652681/000000220000000C/v3_202107300613/S1665268121000181/v3_202107300613/en/main.pdf?idApp=UINPBA00004N&text.app=https://www.elsevier.es/" "EPUB" => "https://multimedia.elsevier.es/PublicationsMultimediaV1/item/epub/S1665268121000181?idApp=UINPBA00004N" ]
