An Unusual Case of Renal-Limited Sarcoidosis Presenting With Hypercalcemia of Unknown Origin: A Case Report.
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
Sarcoidosis is a relatively uncommon multisystem disease that is often difficult to diagnose, frequently requiring multiple physician evaluations. While common symptoms include fatigue, weight loss, lymphadenopathy, and multi-organ involvement, some cases deviate from this classic presentation. We present the case of an elderly male patient who exhibited severe hypercalcemia without the typical systemic manifestations of sarcoidosis. His hypercalcemia of unknown origin led to multiple hospitalizations. Initial medical management provided only temporary relief, and an extensive workup failed to identify a cause. As his condition progressed to acute kidney injury requiring hemodialysis, a more invasive evaluation was pursued. A bone marrow biopsy was unremarkable, but a subsequent kidney biopsy revealed renal-limited sarcoidosis, a rare form of the disease. The patient was started on high-dose corticosteroids, which led to clinical improvement; however, his renal function did not recover sufficiently to discontinue hemodialysis.
