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
backgroundDopaminergic signaling in the Central Nervous System (CNS) has been observed in the pathophysiology of memory deficits. Rotigotine belongs to a non-ergot-based dopamine receptor agonist possessing anti-inflammatory properties. However, it is uncertain if it has a role in ameliorating cognitive decline. Here, we evaluated the actions of rotigotine on neuroinflammation and memory impairment. METHODOLOGY: Rotigotine 1, 3, and 5 mg/kg were administered to mice subcutaneously once a day for fifteen days. Lipopolysaccharide (LPS) 750 µg/kg was administered intraperitoneally for seven days to produce cognitive impairment in mice. Morris water maze and Passive avoidance step-down tests were performed to evaluate memory function. Further, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and amyloid-beta (Aβ) were estimated by ELISA. The mouse brain was analyzed for acetylcholinesterase (AChE) activity, lipid peroxidation, catalase, and reduced glutathione levels.
resultsLPS elevated IL-6, Aβ, TNF-α, and AChE activity, promoted oxidative stress, and caused memory decline in mice. Lower doses of rotigotine 1 and 3 mg/kg significantly reduced neuroinflammation, oxidative stress, and AChE activity, followed by improved cognitive impairment.
conclusionOur data suggest that rotigotine 1 and 3 mg/kg could reverse the neuroinflammation-associated memory impairment.
