The Effort-Based Forage Task: An Ethological Behavioral Test for Assessing Motivation and Apathy-Related Behavior in Mice.
Article in Current protocols, 2025. 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
Apathy and other disorders of motivation represent a significant clinical problem but do not have an agreed treatment approach. The use of translational animal models could facilitate drug development and advance treatment approach. The effort-based forage task provides a readout of motivational state in mouse models based on their intrinsic drive to forage for nesting material. In this task the mouse is placed in an arena composed of an enclosed home area and a foraging area joined via a tube. Throughout the session the mouse can freely choose to traverse the tube to reach the forage area, obtain nesting material, and shuttle it back to the home area. The nesting material requires effort to obtain and is pulled through apertures in a custom designed nesting material box. The amount of nesting material foraged provides a readout of motivational state, where a deficit in foraging indicates a reduction in motivation. The task does not require physiological (food/water) restriction to motivate the animal to perform in the task, and it does not require training beyond initial habituation to the task environment. The task has been used in behavioral phenotyping of disease models and has been used to test the effects of a wide range of pharmacological manipulations on motivational state. The task environment can be altered to test additional behavioral components that contribute to motivational deficit including effort-based modulation of behavior and affective reactivity. Overall, the task provides a rapid, translationally relevant method for understanding changes in motivated behavior independent of physiological restriction at the preclinical level. © 2025 The Author(s).
