Ultrasound-Based Knee Osteoarthritis Severity Assessment and Its Association With Kellgren-Lawrence Grading.
Observational study in TheScientificWorldJournal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Kellgren-Lawrence (KL) grading is a conventional radiography (CR)-based system commonly used to assess osteoarthritis (OA). Knee OA is characterized by damage to the femoral cartilage (FC); however, CR cannot directly visualize cartilage integrity. Ultrasound (US) may be superior in detecting FC damage. This study is aimed at evaluating the US-based knee OA severity assessment and analyze its association with KL grading. Methods: This was an analytical observational study with a cross-sectional design which included knee OA patients. All participants underwent knee US scanning by two independent raters. The severity of knee OA was assessed based on three parameters: the contour of the femoral cartilage, the presence of osteophytes, and meniscus protrusion. The results were accumulated and interpreted into grades from 0 to 4. Association between US-based knee OA assessment and KL grading was analyzed statistically. Results: A total of 112 knee OA patients were included in this study. The average age of participants was 61.4 years, with a higher female prevalence. Grade 3 was the most frequently recorded in both US and KL grades. The US interpretation from both raters showed a perfect agreement based on weighted kappa analysis ( Conclusion: This study demonstrates the US-based knee OA severity assessment and was associated with KL grade.
