The Claim
Between 1965 and 2017, The New England Journal of Medicine, The Lancet, and JAMA collectively published 25.7% of all randomized controlled trial-related articles in high-impact medical journals.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Between 1965 and 2017, three medical journals—The New England Journal of Medicine, The Lancet, and JAMA—published 25.7% of all randomized controlled trial articles in high-impact medical journals.
See the scientific wording
The New England Journal of Medicine, The Lancet, and JAMA collectively published 25.7% of all randomized controlled trial-related articles in high-impact medical journals between 1965 and 2017, reflecting their dominant role in disseminating high-citation clinical research across multiple specialties.
A small number of medical journals publish a large share of high-quality clinical studies because they have strict selection criteria, large readerships, and strong reputations, which causes most important findings to appear in just those few places.
What the research says
1 studyThis study found that three big medical journals—NEJM, The Lancet, and JAMA—published about one out of every four major clinical studies over 50 years, which means they were the most important places for sharing important medical discoveries.
