Elevated plus maze in post-traumatic stress research
From 2021 to 2025, 113 animal research papers on post-traumatic stress mentioned the elevated plus maze in their title or abstract.
That is 1.8 times the 62 papers of 2011 to 2015. Between the same two periods, the papers on post-traumatic stress that mention any of the 90 tests we count grew about as fast, to 1.8 times as many.

Papers on post-traumatic stress that mention the elevated plus maze fell from 24 in 2021 to 16 in 2024, then rose to 31 in 2025. Part of this dip may come from PubMed's indexing rather than from fewer studies. Where PubMed has indexed a paper, we take its disease models from that indexing. Otherwise PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract, or the paper is not counted here. Papers that PubMed indexed under the subject heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025.
Which species the papers used
Each bar is a share of the 113 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 species this chart names.
Tests mentioned alongside the elevated plus maze
Each bar is one test, with how many of the 113 papers also mention it, and what share that is. Of these papers, 25 (22%) mention no other test.

Which papers count
A paper counts here when it is animal research, mentions the elevated plus maze in its title or abstract, and studies post-traumatic stress.
We tell whether a paper studies post-traumatic stress from its MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. For a paper without MeSH terms, PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract. A paper can count under more than one disease model. A paper that mentions the test only in its methods is missed, so the count runs low.
The page on post-traumatic stress research names the subject headings we count as post-traumatic stress. Download the test list for the search terms we used for the elevated plus maze, or the paper list for the PubMed ID of every paper behind these counts. Our main page, Behavioral tests in published research, has the full method and each source's terms of use.
