The effects of a GLP-1 analog liraglutide on reward value and the learned inhibition of appetitive behavior in male and female rats.

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
Liraglutide, a relatively long-lasting analog of glucagon-like peptide-1 (GLP-1), has received recent attention as a treatment for obesity. It has been proposed that activation of GLP-1 receptors in mesolimbic reward pathways contributes to this outcome by reducing hedonic value of food. However, other findings suggest that activation of GLP-1 signaling pathways may suppress appetitive behavior by enhancing a hippocampal-dependent form of learned inhibition. The present experiment compares these two alternatives. Rats first solved a hippocampal-dependent discrimination problem in which a target stimulus signaled the delivery of sucrose, except when it was preceded by an inhibitory cue that signaled nonreward. The effects of 12 daily intraperitoneal (i.p.) injections of liraglutide on responding to the target cue was then compared with and without the inhibitory stimulus. Relative to saline, liraglutide suppressed responding to the target cue only on trials when the inhibitory stimulus was also present (p < .05). This outcome was independent of sex and maintenance diet (Western diet or standard chow). The failure of liraglutide to suppress responding in the absence of the inhibitory cue argues against the notion that this GLP-1 agonist reduced the value of food reward and favors the idea that it enhanced a hippocampal-dependent form of behavioral inhibition.
