Sucrose preference test

From 2021 to 2025, 1,522 animal research papers mentioned the sucrose preference test in their title or abstract, ranking it tenth of the 90 tests we track.

That is 2.8 times the 542 papers of 2011 to 2015. Papers that mention any of the 90 tests grew to 1.2 times as many over the same span.

Papers that mention the sucrose preference test fell from 302 in 2021 to 249 in 2023, then rose to 379 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 1,522 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

786 papers 52%

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 1,186 of the 1,522 papers, so each bar is a share of those 1,186.

C57BL mice
274 papers 23%
Sprague-Dawley rats
266 papers 22%
Wistar rats
122 papers 10%
Knockout mice
27 papers 2%
ICR mice
21 papers 2%
Transgenic mice
18 papers 2%
BALB/c mice
16 papers 1%
Wistar Kyoto rats
10 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 sucrose preference test and study that disease model, with its share of the 1,522 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.

The most cited papers from 2021 to 2025

These papers from 2021 to 2025 mention the sucrose preference test and have the most citations, as counted by NIH's iCite on November 5, 2026. We show four of the five most cited papers and leave out one because of words in its title.

  1. Edaravone ameliorates depressive and anxiety-like behaviors via Sirt1/Nrf2/HO-1/Gpx4 pathway.

    J Neuroinflammation, 2022. 467 citations.

  2. Rifaximin-mediated gut microbiota regulation modulates the function of microglia and protects against CUMS-induced depression-like behaviors in adolescent rat.

    J Neuroinflammation, 2021. 227 citations.

  3. Mechanisms underlying antidepressant effect of transcutaneous auricular vagus nerve stimulation on CUMS model rats based on hippocampal ฮฑ7nAchR/NF-ฮบB signal pathway.

    J Neuroinflammation, 2021. 133 citations.

  4. Sucrose preference test: A systematic review of protocols for the assessment of anhedonia in rodents.

    Eur Neuropsychopharmacol, 2023. 131 citations.

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 sucrose preference test only in its methods is missed, so the count runs low. The count includes 23 reviews. For 336 of the 1,522 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 depression-like behavior tests

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