patients with ulcerative colitis: A cross-sectional study

Reviewer's report:
I have evaluated the manuscript "Association between platelet count and
mucosal healing in Japanese patients with ulcerative colitis: cross-sectional
study" by Furukawa et al. 
The authors evaluated the association between platelet count and MH among
Japanese patients with UC. They showed that platelet count was independently
inversely associated with MH. 
1. They reported other studies evaluating the same issue in their discussion.
However, I would suggest to expand it adding other studies that evaluated also
the rule of platelet count as prognostic marker of treatment response (so, also
MH). One example is the study by Bertani et al. (DOI: 10.1093/ibd/izaa062). 
2. I would suggest to expand the conclusions adding why their study is important
and what it adds to previous knowledge in literature.
