Scope

The BMJ is defined by its mission: to work towards a healthier world for all. We share that global endeavour with millions of readers working in clinical practice, research, education, government, and with patients and the public too. This mission defines us, far more than the format of our content. After nearly 180 years, our print edition still thrives, and has been joined by podcast, video, tweet, app, website and live events. But, as each of these formats gains ground or declines in importance, the things The BMJ cares about will endure: • Improving the creation and dissemination of research evidence • Improving clinical education and practice • Advocating for universal, equitable, high quality healthcare • Championing the health and wellbeing of doctors • Improving the social and environmental determinants of health.

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.
