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
Itoh S, Tanikawa H, Kondo H, Ozeki S, Ito T, Fujimura K, Teranishi T. Minimal Detectable Change in Muscle Strength Measurements Obtained Using a Hand-Held Dynamometer in Patients with Stroke. Jpn J Compr Rehabil Sci 2025; 16: 9-18. Objective: The current study aimed to evaluate the reliability of muscle strength measurements using a hand-held dynamometer (HHD) in patients with chronic stroke. Further, it examined the minimal detectable change (MDC Methods: Patients who presented with chronic stroke hemiplegia for > 180 days post-stroke onset were analyzed. Muscle strength in the paretic lower limb was assessed using an HHD, and gait speed was evaluated. Results: For hip flexion, hip adduction, hip abduction, knee extension, ankle dorsiflexion, and ankle plantarflexion, the intra-rater reliability of the muscle strength measurements, as assessed using the intraclass correlation coefficient (ICC), ranged from 0.989 to 0.998. The inter-rater reliability, as assessed using ICC, ranged from 0.886 to 0.939. Bland-Altman analysis did not indicate systematic errors, and the MDC Conclusions: The HHD had a high reliability in measuring lower limb muscle strength in patients with chronic stroke hemiplegia. Moreover, an association was found between individual muscle strength and gait ability. Based on this study, specific target muscles for interventions that aim to improve gait speed can be identified. Further, the use of MDC
