The Claim

Between 1965 and 2017, the United States produced 46.8% of all randomized controlled trial-related articles published in high-impact medical journals, which was more than double the output of the United Kingdom, and the United States generated 56.5 RCT-related articles per million inhabitants.

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.

In plain English

From 1965 to 2017, the United States published nearly half of all randomized controlled trial articles in top medical journals, more than twice as many as the United Kingdom, and produced 56.5 such articles for every million people in its population.

See the scientific wording

The United States produced 46.8% of all RCT-related articles in high-impact medical journals between 1965 and 2017, more than double the output of the second-leading country, the United Kingdom, and accounted for 56.5 articles per million inhabitants.

Why this might work

The claim describes a pattern of scientific publishing, not a biological process occurring in the human body.

    The study shows that the U.S. wrote almost half of all major medical trials in top journals from 1965 to 2017 — way more than any other country, like the U.K. — which matches what the claim says.
