The hedonic impact of cleaner-client fish interactions is mediated by the opioid system.
Article in Proceedings. Biological sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
According to the 'incentive salience hypothesis' reward processing involves two main components, including the motivation to obtain a reward (i.e. incentive salience or 'wanting') and the hedonic pleasure felt during its consumption (i.e. hedonic impact or 'liking'), which are dissociable. The processing of these hedonic mechanisms is suggested to be mediated by opioid neurotransmission; however, most evidence comes from humans and other mammals. Here we argue that, in mutualistic associations, client fish seek to interact with cleaner fish not only due to the immediate benefits of being cleaned but also because of the hedonic impact of tactile stimulation, modulated by the opioid system. We used a conditioned place preference (CPP) paradigm to test the hedonic dimension of motivation to be cleaned and found that de-parasitized client fish (the butterflyfish
