Evaluation of Various Movement Disorders in Patients of Genetically Proven Spinocerebellar Ataxia: A Study from a Tertiary Care Center in Northern India.
Article in Annals of Indian Academy of Neurology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundMovement disorders are one of the prominent nonataxic symptoms in patients of spinocerebellar ataxia (SCA). The type of movement disorder may provide clinical clue to the type of SCA.
objectiveThe objective of this study is to evaluate various movement disorders in patients of genetically proven SCAs and to establish a probable clinico-genetic correlation.
methodsNinety-Five patients of genetically proven SCAs were assessed for the presence of various movement disorders.
resultsPatients with SCA (75.8% males) with at least one movement disorder contributed 43.16%. Age for onset of movement disorder was 43.39 ± 13.43 years. SCA-12 (38.95%) was the most common subtype. Among the patients with at least one movement disorder, action tremor of hands contributed majority (90.2%). Dystonia and parkinsonism were present in 17.07% and 12.2% of patients (with movement disorder), respectively. Action tremor of hands was present in 34 patients with SCA-12 (91.89%), and 20 patients (54.05%) had onset of hand tremor preceding the onset of ataxia. Majority of patients with SCA-12 (81%) were of the same ethnic origin belonging to Agrawal community. Patients with movement disorder had a later onset (45 ± 13.88 years) of ataxic symptoms compared to those without a movement disorder (32.8 ± 11.92) (
conclusionMovement disorders are present in about 43% of patients with SCA and can precede or succeed the onset of ataxia. Tremor onset SCA predicted SCA-12, especially in Agrawal community.
