JAMA is one of the most prestigious medical journals in the world. As such, it is also one of the most difficult to get published in. The journal receives thousands of submissions each year, and only a small fraction of these are ultimately accepted for publication.
There are a number of factors that contribute to this low acceptance rate. First, JAMA is very selective in the types of articles it publishes. The journal focuses primarily on original research papers, so articles that simply review existing literature or report case studies are less likely to be accepted. Second, JAMA has high standards for the quality of its articles. All submissions must undergo a rigorous peer-review process before being considered for publication, and only those that meet the journal’s high standards will be accepted.
Finally, JAMA gives priority to articles that are likely to have a high impact on the field of medicine. This means that submissions from well-established researchers with a track record of publishing high-quality work are more likely to be accepted than those from less established researchers.
In short, getting published in JAMA is extremely difficult. However, it is not impossible – if you have high-quality data and an article that meets the journal’s criteria, there is a chance your submission will be accepted.
