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

introductionDigital motor outcomes may surpass the sensitivity of clinician-reported outcomes in hereditary spastic paraplegia (HSP), particularly in cases of mild upper limb impairment and early disease stages. We thus validated a trial-ready quantitative motor (Q-Motor) assessment of rapid alternating limb movement tasks against clinician-reported, patient-focused, and performance outcomes in HSP.

methodsExploratory single-center cross-sectional assessment in 41 patients with different HSP genotypes (age: 48 ± 14 years), with speeded foot tapping, diadochokinesia, and finger tapping measured by a high-resolution force transducer. Validation comprised discrimination from 48 age- and sex-matched controls; correlations to the Spastic Paraplegia Rating Scale (SPRS; mean: 18.6 ± 9.1), Friedreich Ataxia Rating Scale- Activities of Daily Living (FARS-ADL), and Nine-Hole Peg Test (9HPT); and stratification by functional stage (FARS stage: mild/moderate/severe = ambulatory/walking aid/wheelchair).

resultsFoot tapping best discriminated patients with HSP from controls (e.g., frequency: area under the curve [AUC] = 0.94-0.96), and particularly captured HSP severity and functional impairment by measures of foot elevation and cumulative tap force (across all measures: |rho

conclusionQ-Motor captures motor impairment in HSP, even in the upper limbs and mild disease stages, and should be further evaluated as a possible trial outcome by longitudinal validation in genotypically stratified cohorts and mapping to patient experience.
