Preventive beneficial effects of cannabidiol in a reserpine-induced progressive model of parkinsonism.

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
Introduction: Parkinson's disease (PD) is characterized by motor and non-motor symptoms such as tremors, difficulty in initiating movements, depression, and cognitive deficits. The pathophysiology of PD involves a gradual decrease in dopaminergic neurons in the substantia nigra, increased inflammatory parameters, and augmented oxidative stress in this region. Several new therapies aim to promote antioxidant and anti-inflammatory actions, including the use of cannabinoids, particularly cannabidiol (CBD). CBD is a non-psychotomimetic component of Objective: The objective of this study was to investigate the potential protective effect of CBD in mice subjected to a low-dose (0.1 mg/kg) repeated reserpine protocol, which encompasses behavioral and neuronal alterations compatible with the progressiveness of PD alterations. Materials and Methods: We used two approaches: (1) concurrent administration during the development of parkinsonism and (2) pre-administration to explore a possible preventive action. The effect of CBD (0.5 mg/kg) on reserpine-induced alterations was investigated on behavioral (catalepsy and vacuous chewing movements) and neuronal (immunolabeling for tyrosine hydroxylase - TH) parameters. Results: Overall, groups that were treated with CBD and reserpine presented motor alterations later during the protocol compared to the groups that received only reserpine (except for vacuous chewing evaluation in the concomitant treatment). Additionally, CBD attenuated reserpine-induced catalepsy (preventive treatment) and prevented the decrease in TH labeling in the substantia nigra pars compacta in both concurrent and preventive protocols. Conclusion: Based on these data, we observed a beneficial effect of CBD in motor and neuronal alterations reserpine-induced progressive parkinsonism, particularly after preventive treatment.
