Here in this post, apart from NEJM Impact Factor, I have tried to compile all the necessary information a research scholar would seek before publishing an article in the journal.

Impact Factor of NEJM
Impact Factor (IF) or often called journal impact factor (JIF) is an index provided by an analytics company named Clarivate. The impact factor is calculated by dividing the number of times the articles are cited in the last two years by the total number of publications in those two years.
For example,
- Total Citations in 2020 and 2021 = 5000
- Total Number of Publications in 2020 and 2021 =Â 500
- Impact Factor of the Journal in 2022 = 500/100 = 10

- NEJM Impact Factor 2017 – 79.258
- NEJM Impact Factor 2018 – 70.670
- NEJM Impact Factor 2019 – 74.699

NEJM H-index
The h index is a metric for evaluating the cumulative impact of an author’s scholarly output and performance; measures quantity with quality by comparing publications to citations.
The h index of NEJM Journal is 1079, which means among all the published articles in this journal, 1079 of these publications have received at least 1079 citations each.
