Concurrence of Pigmented Villonodular Synovitis with Calcium Pyrophosphate Deposition in a Postacute Stroke Patient.
Article in Journal of medical ultrasound. 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
Pigmented villonodular synovitis (PVNS) is a rare synovial proliferative disease featuring hemosiderin deposits. Calcium pyrophosphate deposition (CPPD) is a crystal-induced inflammatory arthritis common in the elderly. We reported the case of a 78-year-old male who was under stroke rehabilitation when acute inflammatory and hemorrhagic knee arthritis of his paretic lower limb occurred. CPPD was proven by synovial analysis. Ultrasonography showed widespread synovial nodular lesions in the affected knee and helped guiding difficult arthrocentesis. These led to a rapid diagnosis of PVNS with magnetic resonance imaging. In elderly stroke patients, knee pain, being a common complaint, warrants a careful diagnosis including adequate imaging. This case demonstrates that ultrasonography is an accessible and useful diagnostic tool.
