Ultrasound-Guided Synovial Biopsy in Chronic Knee Monoarthritis: A Case Series Highlighting Its Diagnostic Value.
Article in Cureus, 2026. 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
Ultrasound-guided synovial biopsy represents a valuable diagnostic tool in the investigation of chronic knee monoarthritis, particularly in cases where conventional clinical, laboratory, and imaging findings remain inconclusive. We report a case series of three patients presenting with chronic knee monoarthritis evolving over several months who were managed in a tertiary rheumatology center. In all cases, ultrasound-guided synovial biopsy was performed after inconclusive routine investigations and enabled definitive etiological diagnosis. Histopathological examination revealed two cases of osteoarticular tuberculosis and one case of localized pigmented villonodular synovitis, thereby allowing timely and targeted therapeutic management. This case series highlights the diagnostic accuracy, safety, and reproducibility of this minimally invasive technique and emphasizes its potential role in reducing diagnostic delays and improving patient outcomes.
