Reviewer’ s report
Title: Evaluation of NAFLD and fibrosis in obese patients –a comparison of histological and
clinical scoring systems
Version: 1Date: 01 Jul 2020
Reviewer: ali bayoumi
Reviewer's report:
1. This reviewer echoes the concern of reviewer 1 in the previous round of version, the difference
between this work and the previous one just recently published by the same group of authors is notclear and there is a concern of duplication.2. According to table 2, the AUOC for APRI index is 0.76 and 0.56 for FIB-4. Hence, the clinicalutility is questionable.3. In table 2, It is not clear why the authors used single cut-off value for APRI and FIB-4, insteadof the routinely used low and high cut-off.4. The characteristics of the cohort seem a typical compared to other large cohorts in literature,,suggesting the potential of selection or referral bias.5. There are various changes in the number of results which was not justified in the responseletter. Sorry, if I missed this.6. The quality of figures and data presentation does not stand to the standards of publication.
