Scope Helicobacter recognises the critical role that has been established for Helicobacter pylori in peptic ulcer, gastric adenocarcinoma, and primary gastric lymphoma. New helicobacter species are now regularly being discovered. By broadening the scope of the Journal to the entire field of helicobacter research, we will increase communication among the various fields such as gastroenterology; microbiology; vaccine development and laboratory animal science. As new discoveries in molecular biology and clinical trials of new treatment open up a wide range of possibilities for patient care and cure, Helicobacter will be there to report the results.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

External Cites per Doc 
Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years.
