How the data was obtained
Data was obtained by performing this search on PubMed.
Explanation of the search terms:
(artificial intelligence[tiab] OR machine learning[tiab]) AND humans[mesh] AND english[lang]
[mesh]refers to MeSH (Medical Subject Headings) which is the vocabulary that PubMed uses to tag and categorize articles. Addinghumans[mesh]excludes things like:- Animal studies (mouse models, rat trials, etc.)
- In vitro / lab studies
- Pure computational/theoretical papers with no human data
[tiab]restricts the search to the title and abstract fields, so only papers that mention AI or machine learning in the title or abstract are included.
