The Impact of Strength/Resistance Training on Related Outcomes of Patients with Knee Osteoarthritis: A Systematic Review and Meta-Analysis Study : Strength/Resistance Training in Knee Osteoarthritis.
Article in Galen medical journal, 2025. 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: The aim of this study was to systematically evaluate and synthesize the available evidence on the effects of resistance/strength training on physical function, stiffness, pain, and quality of life of patients with knee osteoarthritis (KOA). Materials and Methods: A systematic search of electronic databases, including PubMed, Scopus, WOS, and the Cochrane Library, was performed to identify trials published up to December 2024 evaluating the effects of resistance/strength training on KOA. Eligible studies included interventions targeting pain, stiffness, physical function, or quality of life, compared to control or alternative exercise groups. Pooled effect sizes were calculated using fixed and random effects models based on the degree of heterogeneity observed among the studies, with the random effects model applied due to significant variability in outcomes. Results: A total of 21 randomized controlled trials, including 2,345 participants, were analyzed. Resistance training significantly improved physical function (MD=-3.02, P0.01) and reduced stiffness (MD=-0.46; P=0.03). Pain outcomes showed mixed results, with significant reductions observed on the WOMAC pain scale (MD=-0.83, P=0.04), but not consistent effects across other measures such as the VAS. Conclusion: Resistance training improves physical function and stiffness in KOA, with mixed effects on pain and no significant impact on quality of life. High heterogeneity highlights the need for standardized protocols. Resistance training is a valuable component of knee OA management.
