Reviewer’s report:  
 
Please include all comments for the authors in this box rather than uploading your report as an

supporting materials or other a spects of your report which cannot be included in a text format.  
 
Please overwrite this text when adding your comments to the authors.  
 
The study is improved however: a revision by an english native speaker is needed. The authours 
still state everywere that  they studies patients with NAFLD, but in several places in the text is 
would be more appropriate to state that patients with suspected NAFLD were studies (as some 
were not found to suffer from fatty infiltraiton at biopsy).  
 
Page 11 first line. I would suggest to replace "reliable" with "accurate".  
 
I would change the title to a more explicit: Diagnostic accuracy of controlled attenuation 
parameter (CAP) as a non -invasive test for statosi in suspected non alcoholic fatty liver  disease: 
a systematic review and metanalysis.  
 
Page 5: lines 6 -7 the authors state that the informations were retrieved from theprimary articles 
or acquired directly from the corresponding author. However in the reply letter they state that no 
authors of the articles responded to the request to provide individual data. The two statements are 
difficult to go together. Either the authors got in contact with some other authors or they only 
collected data from the primary articles. Please clarify.
