Version: 0Date: 26 Jan 2019
Reviewer: Jianzhong Zhang
Reviewer's report:
The results of this study provide an overview of Helicobacter pylori and NHPGHs infection in
Iranian patients with gastrointestinal diseases. But the article needs to be revised.1. In this paper,the subjects were divided into Helicobacter pylori and NHPGHs positive persons, ignoring thepossible co-infection of the two, which should be supplemented or explained.2. The CT valueused in the judgment result is not explained in the real time PCR part, but should be explained inthe method part. The attached photograph lacks clarity.3. There are only 20 cases of H. salomonis,the most NHPGHs positive case in this study. The stratified analysis of three types of diseases hasno practical significance in statistics. It is enough for all infected persons with pathologicalchanges. The conclusion about the NHPGHs infection is not related to the type of diseases shouldbe revised.
