Multiple Brown Tumors Secondary to Parathyroid Carcinoma: A Challenging Diagnosis.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Parathyroid carcinoma is an extremely rare endocrine neoplasm that accounts for less than 1% of the cases of primary hyperparathyroidism (PHPT). Continuous exposure to high levels of parathyroid hormone (PTH) induces an increase in bone remodeling and patients may present with osteitis fibrosa cystica, which is characterized by subperiosteal resorption of the phalanges, diffuse osteopenia, salt and pepper appearance of the skull, bone cysts, and brown tumors. Brown tumors occur in less than 5% of all patients with any form of hyperparathyroidism. Due to similar clinical, radiographic, and histological appearance, differential diagnosis of brown tumors includes primary and secondary bone tumors. We report a case of a 67-year-old female diagnosed with multiple osteolytic lesions initially thought to be bone metastasis of thyroid carcinoma. Further work-up led to the diagnosis of brown tumors due to parathyroid carcinoma. We want to emphasize the inclusion of osteitis fibrosa cystic in the differential diagnosis of osteolytic lesions and the need to perform serum calcium and PTH measurements when investigating these lesions.
