Exploring the interplay between quantitative muscle strength, functional performance, and patient-reported outcomes in amyotrophic lateral sclerosis: a cross-sectional pilot study.
Trial report in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06199284 (Safety and Efficacy of the Atalante Exoskeleton in the Rehabilitation of Patients With Amyotrophic Lateral Sclerosis), which is not on this 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.

Abstract
Amyotrophic lateral sclerosis (ALS) shows marked clinical heterogeneity, while standard clinical assessments may fail to capture its multidimensional burden. Integrating quantitative muscle strength, functional tests and patient-reported outcomes (PROs) may improve disease characterization. Ten ambulant adults with ALS were enrolled in a cross-sectional pilot study. Functional performance was assessed with the Revised ALS Functional Rating Scale (ALSFRS-R), Six-Minute Walk Test (6MWT), Ten-Meter Walk Test, Timed Up and Go, Berg Balance Scale and a fatigability index, lower-limb strength with dynamometry, and PROs with ALS Assessment Questionnaire-40 (ALSAQ-40), Hospital Anxiety and Depression Scale, Fatigue Severity Scale and Modified Fatigue Impact Scale (MFIS). Despite relatively preserved ALSFRS-R scores (40.6 ± 2.8), participants showed reduced 6MWT (61.3 ± 21.7% predicted), marked fatigability (- 47.3 ± 112.3%) and a lower-limb strength index of 58.2 ± 13.8% predicted. The ALSAQ-40 score averaged 183.1 ± 59.5. Fatigue was prominent, while anxiety and depression remained mild. Muscle strength correlated positively with ALSFRS-R gross motor score and inversely with anxiety. ALSAQ-40 and MFIS components showed significant associations with both functional and walking performance. Even at ambulant stages, measurable muscle weakness and fatigability co-occur with functional and PROs changes in ALS, supporting the use of multidomain, sensitive clinical assessment. The trial was registered at ClinicalTrials.gov (NCT06199284) on 29/12/2023.
