1 · What the graph read from it

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.

2 · The registry

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

Linalool (LIN) is a monoterpene, responsible for the aroma of essential oils in some species. It presents a sedative and anxiolytic potential, enhancing GABAergic currents and behaving as a benzodiazepine-type of drug. The objectives of the present work were to study the neuroprotective effects of LIN on a model of Parkinson's disease. For that, male Wistar rats were divided into the following groups: sham-operated (SO), 6-OHDA-lesioned, and 6-OHDA-lesioned and treated with LIN (25, 50, and 100 mg/kg, p.o.) for 2 weeks. Afterwards, the animals were subjected to behavioral tests (apomorphine-induced rotations, open field, and forced swimming tests). Then, the animals were euthanized, and the striatum, hippocampus, and prefrontal cortex were processed for neurochemistry (nitrite and lipoperoxidation measurements) and immunohistochemistry (TH and DAT) assays. The results were analyzed by ANOVA and Tukey's test for multiple comparisons and considered significant at p < 0.05. LIN significantly improved the behavioral alterations of the 6-OHDA-lesioned group, as evaluated by the apomorphine-induced rotations, open field, and forced swimming tests. In addition, LIN partially reversed the decreased DA, DOPAC, and HVA contents observed in the 6-OHDA-lesioned striatum. The untreated 6-OHDA group presented increased nitrite contents and lipoperoxidation in all the brain areas studied, and these changes were completely reversed after LIN treatments. Finally, LIN significantly prevented the reduction in TH and DAT expressions demonstrated in the right 6-OHDA-lesioned striatum. All these data strongly suggest that LIN presents a neuroprotective action in hemiparkinsonian rats, probably related to the drug anti-inflammatory and antioxidant activities.
