Reviewer's report:
Dear authors,
I read the manuscript titled as "Chronic lead poisoning induced abdominal pain and anemia: a casereport and review of the literature". I think the case report is very interesting and instructive. Afterminor discretionary revisions which I highlighed below I think it would be better. Thank you verymusc for this case report.
1-Is abdominal pain just a two-day complaint? Or is abdominal pain a recurrent complaint? If it is
a new complaint, how would you explain this situation in chronic lead poisoning?2- What do you mean by the expression "inflammatory mediator" in Table 1?
