Dietary supplementation with fish oil reverses high fat diet-induced enhanced sensitivity to the behavioral effects of quinpirole.
Article in Behavioural pharmacology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Consuming a high fat diet can lead to many negative health consequences, such as obesity, insulin resistance, and enhanced sensitivity to drugs acting on dopamine systems. It has recently been demonstrated that dietary supplementation with fish oil, which is rich in omega-3 fatty acids, can prevent this high fat diet-induced enhanced sensitivity to dopaminergic drugs from developing. However, it is not known whether fish oil supplementation can reverse this effect once it has already developed. To test the hypothesis that dietary supplementation with fish oil will reverse high fat diet-induced enhanced sensitivity to quinpirole, a dopamine D2/D3 receptor agonist, male Sprague-Dawley rats were fed either standard chow (17% kcal from fat), high fat chow (60% kcal from fat), standard chow, or high fat chow supplemented with 20% (w/w) fish oil. Body weight, food consumption, and sensitivity to quinpirole-induced (0.0032-0.32 mg/kg) penile erections were examined throughout the course of the experiment. Eating high fat chow enhanced sensitivity of rats to quinpirole-induced penile erections (i.e. resulted in a leftward shift of the ascending limb of the dose-response curve). Dietary supplementation with fish oil successfully treated this effect, as dose-response curves were not different for rats eating standard chow and rats eating high fat chow with fish oil. These results suggest that in addition to preventing the negative health consequences of eating a high fat diet, fish oil can also reverse some of these consequences once they have developed.
