1 · What the graph read from it

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.

2 · The registry

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 non-neoplastic proliferative process that involves synovial tissue in the joints, tendon sheaths and bursae. It usually occurs in young adults, aged 20-50 years, is characteristically monoarticular and of slow progression. Clinical symptoms are nonspecific, and joint stiffness and pain are common in long-term cases. Shoulder PVNS is known to be extremely rare, especially when affecting the subacromial bursal region without joint involvement. Magnetic resonance is the imaging modality of choice in PVNS and is useful for diagnosis, surgical planning and monitoring. Complete surgical synovectomy remains the treatment of choice, and all pathological synovial tissue should be removed. Patients who are not properly treated can progress to joint destruction. We describe a case of PVNS in the subacromial bursa of a 15-year-old patient, with exuberant symptoms and 2 years of evolution, treated with extensive synovectomy and good clinical results in the 1-year follow-up.
