Reviewer's report:
I would like to thank these authors on addressing most of points raised by Reviewrs. As a result, their
submission is now improved. However I feel there remains soom room for further amelioration. For
example these authors should be declare the rationale for evaluating sexes separately (Hepatology.
2019;70:1457-1469) and, importantly, discuss 
the biological meaning of those sex differences they have
identified 
based on previous studies ( J Clin Med. 2020 Apr 28;9(5):1278). English remains to be
improved and some typos also have to be corrected.
