Systemic injection of the DAD1 antagonist SCH 23390 reduces saccharin seeking in rats.
Article in Appetite, 2016. 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
Conditioned cues can elicit drug- and sucrose-seeking behaviors that have been shown to depend on dopamine (DA) D1 receptors. If DAD1 receptors are also involved in seeking behavior in general, blocking these receptors should reduce seeking behavior for a non-caloric, non-drug of abuse reinforcer such as saccharin. Forty-six male Long-Evans rats lever pressed for 0.3% saccharin solution 1 h/day for 10 days. A lever response also activated a tone plus a white stimulus light. This compound stimulus lasted for 5 s. After 1 day of forced abstinence, rats received systemic (0, 1, or 10 μg/kg IP; n = 15-16 per group) injections of SCH 23390 15 min prior to extinction testing. Systemic SCH 23390 reduced saccharin seeking evidenced by a significant reduction in active lever responding and a significant reduction in the number of active lever-contingent deliveries of the tone + light cue following pretreatment with 10 μg/kg SCH 23390. The slope of responding across the Test session in this group was also significantly steeper, indicating that SCH 23390 may have reduced the persistence of saccharin seeking. The results indicate that DAD1 receptors are involved in saccharin seeking and generalize the previously demonstrated anti-seeking effects of DAD1 antagonism to a non-caloric, non-drug of abuse reinforcer.
