The Cerebellar Neuropsychiatric Rating Scale.
Article in Cerebellum (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
The triad of cerebellar ataxiology is the cerebellar motor, vestibular, and cerebellar cognitive affective / Schmahmann syndrome (CCAS). The CCAS affective component comprises 5 domains: Attentional control, Emotional control, Autism spectrum, Psychosis spectrum, and Social Skill Set, each with hypermetric / overshoot and hypometric / undershoot poles reflecting the dysmetria of thought and universal cerebellar transform theories. There is no validated screening instrument to assess neuropsychiatric impairments in patients with cerebellar disorders. To examine the psychometric properties of our Cerebellar Neuropsychiatric Rating Scale (CNRS) that explores these symptoms and behaviors in patients with cerebellar disorders, 21 adults with ataxia completed the CNRS and other validation measures: the Behavior Rating Inventory of Executive Function-Adult Version Informant Report, Adult Behavior Checklist, Older Adult Behavior Checklist, Neuropsychiatric Inventory Questionnaire. We examined CNRS internal consistency using Cronbach's alpha, assessed item to subscale correlations, studied ceiling and floor effects, and convergent construct validity between CNRS and validity measure subscales. Internal consistency was α > 0.70 for each of the five domains. Subscale structure was generally confirmed: 86% of correlations between CNRS and validity subscales were significant. There were no ceiling effects. Item to subscale correlations indicated adequate reliability for total scale and subdomains. NPI-Q and CNRS scores were correlated, and 86.4% (19/22) of conceptually related subscales were significant. The CNRS is a reliable and valid measure of cerebellar neuropsychiatry. Further development can refine the instrument and shed light on the patient experience of their affective dysregulation and its clinical meaningfulness.
