Is Routine Neuroimaging Needed in Adult-Onset Isolated Cervical Dystonia?

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
Background: Clinical practices regarding neuroimaging in isolated cervical dystonia vary across countries and there are no published studies investigating the need of routine neuroimaging in this patient population. Objectives: To investigate if structural neuroimaging is needed in patients with isolated cervical dystonia. Methods: Patients with adult-onset cervical dystonia were identified from a systematic search of the medical records of Turku University Hospital 1996-2022. Clinical and structural neuroimaging data were reviewed by the investigators to evaluate the etiology of dystonia, specifically to identify cases of secondary dystonia caused by structural brain abnormalities. Results: 365 patients with cervical dystonia without other movement disorders with presumed idiopathic or uncertain etiology prior to brain imaging were identified. 282 (77.3%) were scanned using head MRI or CT. Acquired brain lesions were identified in nine (2.5% of all patients) and were significantly more common in patients with vs. without (i.e. isolated) other neurological features ( Conclusions: Routine neuroimaging is not necessary in patients with adult-onset isolated cervical dystonia. Highlights: Studies investigating the need of structural neuroimaging in isolated, adult-onset cervical dystonia are scarce and opinions on this issue are divided among experts.In this study, we reviewed clinical and imaging data of all patients with cervical dystonia with presumed idiopathic or uncertain etiology prior to brain imaging treated at a regional tertiary care hospital between 1996-2022 to investigate the yield of structural brain imaging in these patients.Of the included 365 patients, none showed evidence of progressive neurodegeneration underlying the symptoms and only six (1.6%) showed acquired brain lesions that were considered possibly or likely causal for cervical dystonia.All the six patients with possible or likely lesion-induced cervical dystonia showed cervical dystonia combined with other neurological features, indicating that routine neuroimaging is not needed in isolated, adult-onset cervical dystonia.
