Pathological ankle fracture due to brown tumour: atypical presentation of low serum vitamin D with normal parathyroid hormone and bone profile.
Article in BMJ case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Osteoclastomas or brown tumours are named as such due to increased vascularity, subsequent haemorrhage and haemosiderin deposition giving the lesion a reddish brown appearance under gross microscopic examination. It is due to an increase in parathyroid hormone activity from several causes, such as parathyroid adenomas, renal impairment and low vitamin D levels. The lesions increase the tendency of the bone to fracture. The challenging aspect of the diagnosis is that a histological diagnosis without immunohistochemistry is impossible to make. This is because, without special staining, brown tumours cannot be differentiated from giant cell tumours, which are also classed as benign but can be locally destructive and has potential for malignant transformation. Once tissue diagnosis is confirmed as a brown tumour, then aggressive forms of treatment are not needed, and they generally resolve once the underlying cause is treated. We describe a woman in her 80s who presented to the local Orthopaedic service with a pathological ankle fracture due to a brown tumour.
