The Effect of Rotigotine on Cognitive Function, Daytime Sleepiness, and Sleep Problems in Parkinson Disease: An Open-Label Pilot Study.
Trial report in Clinical neuropharmacology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
backgroundWe hypothesized that rotigotine may have a positive effect on cognitive function in patients with Parkinson disease (PD) by improving daytime motor function and sleep status.
methodsFifteen PD patients with sleep disturbances, defined as a PD Sleep Scale (PDSS)-2 score of 15 or greater, were included in this single-center, 3-month open-label study. Participants received 2 to 4 mg/24 h (patch content: 4.5-9 mg) rotigotine for a 3-month period. At baseline and 3 months, the patients were evaluated on the Movement Disorder Society Revision of the Unified PD Rating Scale (MDS-UPDRS) parts III and IV and cognitive assessments, such as the Mini-Mental State Examination, frontal assessment battery, and Montreal Cognitive Assessment (MoCA). The Epworth Sleepiness Scale (ESS) and PDSS-2 were administered at baseline and at 1, 2, and 3 months.
resultsAt 3 months, the MDS-UPDRS part III (-11.1, P < 0.0001) and MDS-UPDRS part IV (-1.1, P = 0.0013) scores significantly decreased, and off time significantly decreased (-34.6 minutes, P = 0.0085) from baseline. The PDSS-2 scores significantly decreased from baseline at 1 month (-4.2, P < 0.01), 2 months (-7.7, P < 0.0001), and 3 months (-7.3, P < 0.0001). The ESS also decreased at 1 month (-2.5, P < 0.05) and 3 months from baseline (-4.5, P < 0.01). The MoCA scores (1.6, P = 0.0029) significantly improved, but the Mini-Mental State Examination or frontal assessment battery scores did not significantly change. The mean changes from baseline to 3 months in the MoCA were negatively correlated with mean changes in the ESS scores.
conclusionsWe suggest that rotigotine could improve cognitive function by improving motor symptoms, sleep disturbance, and daytime sleepiness in patients with PD.
