Fine-tuning of dopamine receptor signaling with aripiprazole counteracts ketamine's dissociative action, but not its antidepressant effect.

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
Ketamine, a rapid-acting antidepressant, has undesirable psychotomimetic effects, including a dissociative effect. There is currently no effective strategy to suppress these side effects while preserving its antidepressant effect. Here, we investigated the effects of a D2/D3 receptor antagonist and partial agonists on the psychotomimetic and antidepressant effects of ketamine in mice and humans. Aripiprazole, a partial agonist, attenuated the psychotomimetic effect, but maintaining and even enhancing the antidepressant-like effect of ketamine in the forced swim test, whereas raclopride, an antagonist, suppressed both effects in mice. Brain-wide Fos mapping and its network analysis suggested the ventral tegmental area (VTA) as a critical region for distinguishing the effects of aripiprazole and raclopride. In the chronic stress model, local infusion of raclopride into the VTA inhibited ketamine's antidepressant-like effect, accompanied by activation of dopaminergic neurons, suggesting the inhibitory effect of VTA activation on the antidepressant-like effect of ketamine. Consistently, systemic injections of raclopride and brexpiprazole, a partial agonist similar to aripiprazole but closer to an antagonist (lower E
