Association of upper limb motor function with muscle tone changes and quality of life in the subacute phase after stroke: a prospective cohort study.
Article in Frontiers in neurology. 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
Background: Changes in muscle tone after stroke may influence upper limb (UL) motor recovery and quality of life (QoL), but their relationship remains unclear. This study evaluated associations between muscle tone changes, UL motor function, and QoL in patients undergoing subacute stroke rehabilitation. Methods: This prospective cohort study is a secondary analysis of data from a randomized controlled trial including 58 patients in the subacute phase after stroke. UL motor function was assessed using the Fugl-Meyer Assessment (FMA-UE) and Box and Blocks Test (BBT), muscle tone using myotonometry, and QoL using the EuroQol-5 Dimensions-5 Levels (EQ-5D-5L) questionnaire. Correlations between changes in these parameters were analysed. Results: Most changes in muscle tone were not significantly associated with improvements in upper limb motor function or quality of life. Only isolated, weak correlations were observed, including negative associations between changes in the total score of the Fugl-Meyer Assessment for Upper Extremity and changes in relaxation time of the flexor digitorum superficialis muscle measured using myotonometry ( Conclusion: UL motor recovery may occur largely independently of changes in muscle tone and is more closely associated with QoL. Rehabilitation should prioritise motor control and functional performance rather than focusing primarily on tone reduction.
