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
The biochemical and molecular substrates of methamphetamine (METH) use disorder remain to be elucidated. In rodents, increased METH intake is associated with increased expression of dopamine D1 receptors (D1R) in the dorsal striatum. The present study assessed potential effects of inhibiting striatal D1R activity on METH self-administration (SA) by rats. We microinjected Cre-activated adeno-associated viruses to deliver the inhibitory DREADD construct, hM4D (Gi) - mCherry, into neurons that expressed Cre-recombinase (D1-expressing neurons) in the dorsal striatum of male and female transgenic Long Evans rats (Drd1a-iCre#3). Two weeks later, we trained rats to self-administer METH. Once this behavior was acquired, intraperitoneal injections of clozapine-N-Oxide (CNO) or its vehicle (sterile water) were given to rats before each METH SA session to determine the effect of DREADD-mediated inhibition on METH intake. After the end of the experiments, histology was performed to confirm DREADD delivery into the dorsal striatum. There were no significant effects of the inhibitory DREADD on METH SA by male or female rats. Post-mortem histological assessment revealed DREADD expression in the dorsal striatum. Our results suggest that inhibition of D1R in the dorsal striatum does not suppress METH SA. It remains to be determined if activating D1R-expressing neurons might have differential behavioral effects. Future studies will also assess if impacting D1R activity in other brain regions might influence METH SA.
