Anxiety
From 2021 to 2025, 3,041 animal research papers on anxiety mentioned at least one behavioral test, most often the elevated plus maze.
That is 1.3 times the 2,358 papers of 2011 to 2015. Papers that mention any of the 90 tests grew to 1.2 times as many over the same span.
The tests these papers mention
The elevated plus maze appears in 51% of the papers on anxiety and in 8.9% of all 32,277 papers that mention a test. That makes it 5.7 times as common in this research. Each bar counts the papers from 2021 to 2025 on anxiety that mention the test, with its share of the 3,041 papers. A paper that mentions two tests counts under both.

Papers on anxiety fell from 642 in 2021 to 494 in 2023, then rose to 771 in 2025. Papers that PubMed indexed under the MeSH heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025. We take each paper's disease models from PubMed's indexing whenever PubMed has indexed the paper, so part of this dip may come from the indexing rather than from fewer studies.
Which species the papers used
Each bar is a share of the 3,041 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.
Species
“Other animals” counts papers that use none of the other species in this chart.
Which papers count
A paper counts here when it is animal research, mentions at least one of the 90 tests and studies anxiety.
A paper counts under anxiety when its MeSH terms, the subject headings PubMed adds when it indexes a paper, include one of these.
- Anxiety
- Anxiety Disorders
- Panic Disorder
- Phobic Disorders
For a paper PubMed has not indexed, PubTator 3, NCBI's text-mining service, supplies the disease model when it finds the disease in the title or abstract. A paper can count under more than one disease model.
Each paper and its disease models are in the downloads. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.
