This study identified classic papers by referring to the Science Citation Index Expanded, which covers 59,904 documents related Helicobacter pylori publications in the Web of Science from 1900 to 2016. The present paper lists classic Helicobacter pylori papers published between 1991 and 2007.

An article published by Parsonnet et al. in 1991 obtained the highest number of citations from the Web of Science Core Collection during the period from its initial publication to the end of 2016. The most impactful article in 2016 was published by Uemura et al. in 2001 with 163 citations in 2016. In addition, results showed that three main research focuses in H. pylori study were gastric cancer, low-grade gastric lymphoma, and the CagA gene.
