Title: Evaluation of NAFLD and fibrosis in obese patients –a comparison of histological and
clinical scoring systems
Version: 0Date: 03 May 2020
Reviewer: Stefano Bellentani
Reviewer's report:
This interesting manuscript the authors explore the correlation between different fibrosis non-
invasive scores and histology in a cohort of 141 obese patients who undergo to bariatric surgery.The biopsies were taken by a piece of the left lobe of the liver. The statistical analysis of the data isgood, and the results are well illustrated and explained. The conclusions are strong and wellcorrelated to the results obtained, and demonstrated that APRI score, that is the most simple non-invasive score, was the best one to use.I think this paper deserve publication in BMC Gastroenterology with minor revision, particularly:1- Please don't use "index" instead of "score", and substitute index in all the manuscript2- Table 1 is not compact and the data are spread out... Try to compact it3- English language needs a more accurate revision
