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
Cannabidiol (CBD) is a compound found in Cannabis sativa that is known for its neuroprotective, anti-inflammatory, analgesic, and anxiolytic properties. These properties make it a promising treatment for various neurological conditions. This study aimed to examine the effects of CBD on hypothalamic neurons at the transcriptome level using the adult-derived mHypoA-2/12 mouse cell line. The cells were exposed to four different CBD concentrations (ranging from 0.325 to 3 µM) for 6 and 24 h. Apart from the transcriptome analysis, apoptosis (caspase 3/7 activity) and viability (MTT) assays were performed. The obtained results showed that CBD enhanced cell viability, especially after 24 h of treatment and at lower or intermediate concentrations, and reduced apoptosis, with significant effects at the highest concentration. CBD caused moderate transcriptome profile changes (13 to 69 genes per treatment), with more genes affected at higher concentrations and shorter exposure times, indicating a stronger initial cellular response. Further analysis revealed that CBD affects several biological processes, including: intrinsic apoptosis suppression via p53 modulation, impacting genes like Bbc3, Mdm2, Cdkn1a, and Smad3. Additionally, CBD influenced genes involved in extracellular matrix organization, including metalloproteinases (Mmp-3, Mmp-13) and their inhibitors (Timp1), as well as collagen components (Col11a1) and mitochondrial respiratory chain complexes (mt-Nd5, mt-Nd4). Genes related to serotonin and dopamine biosynthesis, as well as Aldh2, were also impacted, linking CBD's effects in hypothalamic neurons to potential benefits in managing alcohol use disorders. These findings suggest the hypothalamus is a significant target for CBD, warranting further investigation.
