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
backgroundParkinson's disease is defined by the loss of dopaminergic neurons in the midbrain of substantia nigra associated with Lewy bodies. The precise mechanism is not yet entirely understood.
objectiveThe study aims to determine whether ocimene has antiparkinsonian activity by reducing α-Synuclein aggregation levels in the brains of rotenone-induced rat models.
methods36 male rats were used for six groups, with six animals in each group. Vehicle, control (rotenone, 2.5 mg/kg, i.p), standard (L-Dopa, 10 mg/kg, i.p), Test drug of low dose (66.66 mg/kg, i.p), medium dose (100 mg/kg, i.p), and high dose (200 mg/kg, i.p) were administered to the rats. The open field, actophotometer, hanging wire, and catalepsy tests were used to assess the rat's motor performance. The expressions of biomarkers such as AchE, D2 Receptor, and α- Synuclein were evaluated, and their level of expression in the brain samples was checked using ELISA. Histopathological analysis was also carried out to determine the degree of neuron degeneration in the brain samples.
resultsThe open field test showed significant anxiety levels, whereas test groups showed fewer anxiety levels but increased motor activity. The biochemical tests revealed that rotenonetreated rats had higher levels of AchE, but ocimene-treated rats had a significant decrease in AchE levels. The test drug-treated rats also expressed high levels of D2 receptors. In ocimenetreated rats, α-Synuclein aggregation was reduced, however, in rotenone-treated rats' brain samples, higher clumps of α-Synuclein were observed.
conclusionOcimene has neuroprotective properties. As a result, this essential oil might be helpful as a therapeutic treatment for Parkinson's disease.
