A case report: Neuroimaging in an atypical presentation of Parkinson's disease.

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 the second leading neurodegenerative disorder in the world. The diagnosis of idiopathic Parkinson's disease (IPD) is mainly through clinical presentation of motor and non-motor symptoms. Motor symptoms include tremor, bradykinesia and rigidity. Atypical parkinsonism may pose a challenge in diagnosing IPD. Functional neuroimaging can assist in diagnosing IPD and in differentiating it from atypical parkinsonism due to other neurodegenerative aetiologies. Patient presentation: We present a case report of a patient with atypical parkinsonism and mild neurocognitive disorder. Management and outcome: Neuroimaging revealed IPD, distinguishing it from other causes of neurocognitive disorders. The patient received multidisciplinary team (MDT) input and appropriate medication, including a fixed combination of carbidopa and levodopa, rivastigmine, venlafaxine and quetiapine with improvement of his symptomatology. Conclusion: Neuroimaging assisted in establishing the diagnosis and guiding treatment. Contribution: Although evidence and studies are needed for definitive use in clinical practice, there is supportive evidence to suggest the diagnostic utility of these modalities in parkinsonian syndromes.
