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
Methamphetamine addiction remains a major public health concern in the United States that has paralleled the opioid epidemic. Psychostimulant use disorders have a heritable genetic component that remains unexplained. Methamphetamine targets membrane and vesicular transporters to increase synaptic dopamine, norepinephrine, and serotonin. We previously identified Hnrnph1 (heterogeneous nuclear ribonucleoprotein H1) as a quantitative trait gene underlying methamphetamine behavioral sensitivity. Hnrnph1 encodes the RNA-binding protein hnRNP H1 that is ubiquitously expressed in neurons throughout the adult brain. Gene-edited mice with a heterozygous frameshift deletion in Hnrnph1's first coding exon showed reduced methamphetamine-induced dopamine release and behaviors. To potentially inform the mechanism linking hnRNP H with methamphetamine behavior, we surveyed the mRNA targetome of hnRNP H via cross-linking immunoprecipitation coupled with RNA-sequencing in striatum at baseline and at 30 min post-methamphetamine in wild-type female and male C57BL/6 J mice. Methamphetamine induced changes in RNA-binding targets of hnRNP H in mice, including 3'UTRs of enriched mRNAs involved in synaptic plasticity. Targetome, transcriptome, and spliceome analyses triangulated on Cacna2d2 which showed methamphetamine-induced changes in hnRNP H binding, gene expression and splicing. Pre-treatment with pregabalin, an inhibitor of CACNA2D2 and CACNA2D1 voltage-gated calcium channel subunits, attenuated methamphetamine-induced locomotor activity, suggesting CACNA2D2 could contribute to methamphetamine locomotor stimulant sensitivity. Our study identifies a dynamic hnRNP H RNA targetome that can respond rapidly to methamphetamine and could potentially contribute to synaptic plasticity and behavior. Given our discovery-based findings, future studies will require directly validating the link between methamphetamine-induced changes in hnRNP H binding, gene regulation, synaptic plasticity, and behavior.
