1 · What the graph read from 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.

2 · The registry

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

backgroundClinical trials in spinocerebellar ataxias (SCA) require objective, quantifiable outcome measures sensitive to changes in disease severity.

objectivesThe objective was to study the sensitivity to change of digital gait biomarkers in SCA1 over a 1-year period.

methodsSeventeen SCA1 patients and 15 controls walked 30 seconds wearing 3 sensors at 3 walking speeds (preferred, slow, fast) at baseline and 1-year follow-up. Relationship between gait and clinical measures was analyzed, and standardized response means (SRMs) were calculated.

resultsToe-off angle (TOA), variability in TOA, speed, and stride length showed significant responsiveness (SRM = -1.15, 0.61, -0.77, and -0.85). TOA, which correlated most strongly with ataxia severity and patient-reported outcomes, demonstrated higher sensitivity to change than Scale for Assessment and Rating of Ataxia (SARA) in early-stage disease at preferred walking speed. Gait variability measures lacked sensitivity, possibly due to the short recording period.

conclusionsDigital gait biomarkers are promising outcomes in future clinical trials in SCA1, but their sensitivity to change appears stage dependent.
