Quantitative ultrasound assessment of gastrocnemius muscle changes in patients with knee osteoarthritis.

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
BackgroundKnee osteoarthritis presents with posterior knee pain, stiffness, and restricted mobility, potentially affecting periarticular muscle biomechanics. We ultrasonographically assessed the gastrocnemius medialis properties in patients with knee osteoarthritis compared with those in healthy controls.MethodsThis study comprised 76 participants divided into symptomatic patients with knee osteoarthritis and gastrocnemius medialis involvement and healthy controls. Gastrocnemius medialis morphology (thickness and pennation angle) was evaluated using conventional ultrasound, whereas shear touch elastography was applied to assess tissue stiffness via elasticity (Gmean).ResultsGastrocnemius medialis thickness was similar between the groups (p
