Performing the identical exercise for the NEJM, we see differences that are quite striking. The top four journals are there: NEJM, Annals of Internal Medicine, JAMA, and Archives of Internal Medicine, but the next two are cardiology journals, as are 9 of the next 12 journals shown.
While this observation does not affect the categorization of NEJM as a general medicine journal, the next slide will demonstrate further that it is relevant to list it in the cardiology category, as well.
