The new tool
On 24 September, the US National Library of Medicine announced Linked Discoveries. Starting from an eligible PubMed article, the experimental tool builds an AI-informed network of related papers and connected biomedical information. Its neighbourhood can contain up to 200 publications. [1, 2]
The useful distinction
A map can reveal an unfamiliar research branch or a connection between topics. It cannot establish that the papers agree, that a result replicated, or that an attractive connection is causal. Readers still need to inspect the studies.
What to keep in mind
Linked Discoveries is a pilot, not an evidence-grading system. A visible connection is a lead to investigate, not a scientific conclusion.
