Multiple spinal brown tumors presenting as compressive thoracic myelopathy in a patient on maintenance hemodialysis.

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
Brown tumor, also known as osteitis fibrosa cystica, is a benign bone lesion due to excessive lytic action by osteoclasts, in the presence of primary, secondary, or tertiary hyperparathyroidism. Due to early screening, they are a rare occurrence. This report presents a case of a 47-year-old man on regular hemodialysis presenting with compressive thoracic myelopathy. Based on elevated parathyroid hormone, imaging, and histopathology, the diagnosis of brown tumor was confirmed. He then underwent tumor excision, following which the underlying secondary hyperparathyroidism was treated with calcitriol and calcium replacement. Though secondary hyperparathyroidism is a common complication of chronic kidney disease, brown tumors are a rare manifestation and uncommonly located in the spine. Differential diagnoses include metastatic lesions, plasmacytomas, giant cell granulomas, or simple bone cysts. Early diagnosis and management of a spinal brown tumor can prevent neurological complications.
