Title:Green tea consumption and risk of esophageal cancer: a meta-analysis of
epidemiologic studies
Version: 2Date:9 September 2012
Reviewer: Ellen E Kampman
Reviewer's report:
The authors have responded to my comments. Because of the language barrier,
it is difficult to judge, however, whether all changes suggested were indeed
included in the text.
The fact that women have a decreased risk could not only be due to hormonal
factor, but, and I do find this more important, to the fact that female studies were
case-control studies, were conducted in China, and that the number of studies
were limited. I would suggest the hormonal mechanism only after mentioning all
the other possibilities.
Level of interest: An article whose findings are important to those with closely
related research interests
Quality of written English: Not suitable for publication unless extensively edited
Statistical review: No, the manuscript does not need to be seen by a
statistician.
