Personal Social Network Analysis in Cerebellar Ataxia: Exploring Correlations with Quality of Life and Functional Outcomes.
Article in Cerebellum (London, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Patients with cerebellar ataxia experience fatigue, impaired executive function, and psychosocial deficits. Personal social networks affect physical and mental well-being but there are no data on their effect on quality of life (QOL) and function in ataxia. We examined social network metrics in patients with cerebellar ataxia to test the hypothesis that supportive relationships enhance quality of life and physical function. We used a cross-sectional, survey-interview design with the Personal Network Survey for Clinical Research, World Health Organization QOL-BREF (WHOQOL), Functional Staging Scale for Ataxia, Friedreich's Ataxia Rating Scale-Activities of Daily Living (FARS-ADL), and Patient-Reported Outcome Measure of Ataxia (PROM-Ataxia). We used univariate and bivariate descriptive statistics and bivariate correlations to explore relationships between social network characteristics and QOL, and multivariable linear regression for associations between them. In 106 ataxia patients (56 ± 15.3 years), social network size averaged 7.6 ± 2.8 people, mostly friends (52%) and family (33%). Social networks were dense (0.7 ± 0.3) and constrained (0.5 ± 0.1). Omnibus test showed that positive relationships, camaraderie, weekly communication, and high levels of emotional support correlated with PROM-Ataxia Total (p = 0.03), PROM-Ataxia Mental health (p = 0.05), WHOQOL (p = 0.03), FARS-ADL and Functional Staging. Those with constrained social networks and fewer positive relationships reported low QOL, as did those with frequent therapy/counseling and organizational involvement. Positive relationships within social networks of cerebellar ataxia patients positively influence QOL and functional measures. Counterintuitive negative associations with external sources of support need further study to explore causality. Network interventions to enhance emotional support and camaraderie may improve quality of life.
