Figure 2. Distribution of highly frequent words in cell biology and medicine journals. We distributed the 40 most frequent words in titles and abstracts of articles from Journal of Cell Biology (JCB), Journal of Cell Science (JCS), New England Journal of Medicine (NEJ), and Lancet (Lan). There was a remarkable vocabulary similarity between JCB and JCS (28 shared words compared to (6+4) unique words), as well as between NEJ and Lan (19 shared words compared to (13+15) unique words). There was a large difference in vocabulary between cell biology and medicine journals, with only 5 words in common.
