It connects research in Internal medicine with the related topic of Cardiology. The research on Cohort study featured in the journal combines topics in other fields like Interquartile range and Cohort. The journal links adjacent topics like Randomized controlled trial with Psychological intervention.

Papers citation over time

A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.

The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 9.63% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 47.12% were posted by at least one author from the top 10 institutions publishing in the journal. Another 9.17% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 12.79% of all publications and 30.92% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

• Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
• Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
• Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
• Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
• Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.

Educational Background of Authors

A significant factor that might influence the quality of research and topics covered in JAMA Internal Medicine is the educational background of the authors who contribute to the journal. One may wonder where these authors obtained their medical degrees and what were their major areas of study. It would be insightful to consider the most reputable nursing and medical schools from which these authors graduated. Here, it might be interesting to note that some of these authors may have received their degrees from some of the leading nursing institutions. For instance, some may have graduated from one of the top nursing schools in Alaska. A prestigious academic background can significantly contribute to the quality and depth of research, assuming solid training and a robust educational foundation. Knowing the education history of the authors can provide insight into the influences shaping the research presented in JAMA Internal Medicine. It may also highlight any potential academic biases or strengths inherent in the articles published by the journal. Further, understanding the educational roots of the authors could aid in assessing the relevance of the research to different regional contexts – particularly if the authors have graduated from institutions with strong regional health specialties.
