Challenging Medical and Surgical Management of Ectopic Parathyroid Hormone (PTH) Adenomas in the Elderly.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Ectopic parathyroid adenomas (EPAs) are rare and difficult to localize, making surgical cures challenging on the first attempt. However, the management of EPAs in the literature on the geriatric population is limited. Herein, we report two elderly cases of EPAs in atypical locations and challenging management with a mini review of the literature. An 82-year-old English male presented with confusion and constipation, and his tests confirmed primary hyperparathyroidism (PHPT). However, IV fluids and IV bisphosphonate treatment did not treat his hypercalcemia and imaging investigations could not localize parathyroid adenoma (PA); therefore, he underwent explorative left-sided parathyroidectomy, which confirmed normal parathyroid gland. His hypercalcemia improved shortly after surgery; nonetheless, a month later, he was readmitted with recurrent hypercalcemia symptoms. Single-photon emission computed tomography (SPECT) showed a nodule in the mediastinum referring to EPA. But the patient refused the second mediastinal surgery, and after MDT discussion, medical treatment with Cinacalcet was started. Finally, his calcium was normalized under this treatment and remains so. A 69-year-old Turkish female presented with generalized bone pain, and she was diagnosed with PHPT. Her imaging investigations showed only one 1.6cm nodule in the thyroid, and no PA was detected. Further, fine needle aspiration parathyroid hormone (PTH) wash-out from that thyroid nodule showed very high PTH levels, referring to the thyroid's EPA. Meanwhile, she was screened for complications of PHPT, and nephrolitiasis and kyphosis due to severe osteoporosis were found. She underwent minimally invasive surgery under local anesthesia due to severe kyphosis for this EPA, which was confirmed by histopathology. Her PTH and calcium levels normalized shortly after surgery. In limiting imaging results, PTH wash out could be helpful in diagnostic challenges, especially in suspected nodules/lesions in the neck. For the elderly, the value of surgery in achieving a cure is less straightforward than for the young. Thus, treatment of EPAs in the elderly should be decided based on comorbidities, difficult atypical localizations of EPAs and patients' preferences.
