Papers that mention the elevated plus maze fell from 583 in 2021 to 521 in 2023, then rose to 657 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 species from PubMed's indexing whenever it names one, 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 2,883 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

Species

Rat
1,462 papers 51%
Mouse
1,451 papers 50%
Other animals
48 papers 2%
Zebrafish
4 papers under 1%

โ€œOther animalsโ€ counts papers that use none of the other species in this chart.

Strains and genetic lines

Strain names come from the MeSH terms PubMed adds when it indexes a paper. PubMed has indexed 2,227 of the 2,883 papers, so each bar is a share of those 2,227.

Wistar rats
501 papers 22%
C57BL mice
402 papers 18%
Sprague-Dawley rats
295 papers 13%
Knockout mice

Transgenic mice
51 papers 2%
BALB/c mice
44 papers 2%
ICR mice
29 papers 1%
Long-Evans rats
27 papers 1%

A paper indexed under two of these headings, such as knockout mice and a strain, counts under both.

Disease models these papers study

Each bar counts the papers from 2021 to 2025 that mention the elevated plus maze and study that disease model, with its share of the 2,883 papers. The model comes from a paper's MeSH terms. For a paper PubMed has not indexed, it comes from PubTator 3, NCBI's text-mining service, when that service finds the disease in the title or abstract. A paper can count under more than one model.

Tests mentioned alongside the elevated plus maze

Each bar counts the papers from 2021 to 2025 that mention both tests, with its share of the 2,883 papers that mention the elevated plus maze.

Papers from 2021 to 2025 that mention both tests

How we counted

A count is the number of animal research papers whose title or abstract mentions one of the test's search terms. It is not a count of experiments, labs or animals.

A paper that mentions the elevated plus maze only in its methods is missed, so the count runs low. The count includes 29 reviews. For 656 of the 2,883 papers, PubMed's indexing gave no species, so the species came from PubTator 3 finding one in the title or abstract.

The test's search terms are in the test list download. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.

More anxiety-like behavior tests

These anxiety-like behavior tests also have a page, with their papers from 2021 to 2025. Each test with 30 or more papers gets one.
