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.

Self-Cites

Evolution of the total number of citations and journal's self-citations received by a journal's published documents during the three previous years.
Journal Self-citation is defined as the number of citation from a journal citing article to articles published by the same journal.

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. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.

ISSN	17527155, 17527163
Coverage	2008-ongoing
Scope	This journal is dedicated to all aspects of breath science, with the major focus on analysis of exhaled breath in physiology and medicine, and the diagnosis and treatment of breath odours. It covers research into use of breath science for diagnosing and monitoring systemic health, lung- and oesophageal cancer, lung and bronchial disease and infection, monitoring alcohol intake, detecting exposure to smoke and to workplace and home contaminants, diagnosing and treating halitosis and oral diseases, testing physiological aspects of breathing and respiration (oxygenation, carbon dioxide, moisture, capacity, rate), testing for oxidative stress and psychological stress and anxiety, identifying sleep apnoea and investigating acid reflux cough.
