Clinical and neuroimaging correlates of disease related gait patterns in patients with multiple system atrophy cerebellar type.

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
Multiple system atrophy-cerebellar type (MSA-C) is a rapidly progressive neurodegenerative disorder, yet objective digital biomarkers for disease severity remain scarce. This cross-sectional study aimed to identify disease-relevant gait patterns using a 2D video-based gait analysis algorithm and examine their clinical and neuroimaging correlates. Gait features were extracted from videos of patients with MSA-C using Gaitome, and an MSA-C gait pattern score was derived. This score significantly distinguished MSA-C from healthy controls (area under the curve = 0.98) and showed significant correlations with UMSAR part I (r = 0.49, p = 0.0014), part II (r = 0.51, p = 0.0014), MMSE (r = - 0.43, p = 0.012), and MoCA (r = - 0.34, p = 0.049). Tractography revealed significant associations between the gait score and structural connectivity in the middle cerebellar peduncle, cerebellum, and cingulate. Voxel-based morphometry showed that the gait score correlated with gray matter volume in the middle temporal and cerebellar regions, whereas UMSAR part II did not show significant structural associations. These findings suggest that gait patterns extracted from a single video camera can reflect both motor and cognitive severity in MSA-C, and may serve as a practical, non-invasive digital biomarker for disease monitoring.
