However, using the JCR relatedness ranking method, some journals would be assigned to different JCR categories. Using Circulation, the highest impact journal in this area, to represent cardiology, we find that NEJM ranked 7th among the most related journals in this field.
Heretofore one could only guess at the proximity of NEJM to this or other topics. However, this analysis also tells us something about the JCR placement of the journal Coronary Artery Disease. JCR assigns it to the category “Peripheral Vascular Disease” but it is in fact the 10th
journal in this list.
