Transient strain differences in an operant delayed non-match to position task.
Article in Behavioural processes, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Working memory refers to the temporary retention of a small amount of information used in the execution of a cognitive task. Working memory impairments are one of the common hallmarks of many neuropsychiatric and neurological disorders including schizophrenia and Alzheimer's disease. Here, we investigated Fischer 344 and Long-Evans rats for strain and sex differences in working memory using the operant-based DNMTP task. Rats were required to press one of two levers presented during a sample phase and followed by a 2-32 second delay, the rats were then required to press the opposite, nonmatch, lever during the choice phase. We found a transient strain difference with Fischer 344 rats performing better than Long-Evans early in training. The Fischer 344 strain showed stable performance across sessions while the performance of Long-Evans increased in the later sessions. Since different background rat strains are used for transgenic rat models, it is critical to be able to compare the behavioral performance across different strains. These findings have implications in behavioral neuroscience research as understanding the typical behavioral endpoints in different background strains will aid our understanding of how different models affect behavioral performance.
