Case report: A rare case of retroperitoneal mixed type unicentric Castleman disease.
Article in Frontiers in oncology, 2026. 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
Objective: To enhance the understanding, diagnosis, and management of retroperitoneal mixed type unicentric Castleman disease. Methods: This report describes a case of retroperitoneal mixed type unicentric Castleman disease managed at our institution. The clinical presentation, histopathological characteristics, and therapeutic approach are detailed. A discussion regarding the current status of diagnosis, management, and prognosis is provided, supplemented by a review of the relevant literature. Results: A 52-year-old female was admitted with a chief complaint of "frequent urination for over 6 months." A retroperitoneal mass was identified. The patient underwent laparoscopic excision of the retroperitoneal mass. Postoperative pathological examination confirmed the diagnosis of mixed type unicentric Castleman disease. The patient's postoperative recovery was uneventful, and she remains under close follow-up surveillance. Conclusion: Retroperitoneal mixed type unicentric Castleman disease is clinically uncommon and possesses distinctive histopathological features. Awareness of this entity needs to be heightened.
