Structure-function association of the cerebellar motor network is altered in 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
backgroundCervical dystonia (CD) has been recognized as a disorder of the brain's sensorimotor network. Within this malfunctioning network, the cerebellum plays an important role that needs to be further characterized.
methodsTo investigate the structural connectivity of the dentato-rubro-thalamic tract (DRTT), probabilistic tractography was performed in 18 CD patients and 18 matched healthy control (HC) subjects. Connectivity was quantified with fractional anisotropy (FA). Thirteen subjects in each group also participated in a neurophysiological double-blind experiment to investigate the effect of cathodal and sham cerebellar transcranial direct current stimulation (ctDCS) on sensorimotor associative plasticity, as evoked by paired associative stimulation (PAS). The association of FA of the DRTT and neurophysiological parameters was studied with linear models.
resultsThe FA of the DRTT was not different between the groups and not related to motor symptom severity in CD patients. In the HC group, there was a significant association between the structural connectivity of the DRTT and the effect that cathodal ctDCS had on the PAS effect. This association was not found in CD patients.
conclusionsThe microstructural state of the DRTT is a potential biomarker for the efficacy of ctDCS in HC. The lack of this structure-function association in patients is further evidence of abnormal properties of the cerebellar motor network in CD.
