A Case of Clear Cell Papillary Renal Cell Tumor: A Rare Entity With an Unusual Presentation.
Article in Clinical case reports, 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
Clear cell papillary renal cell Tumor (CCPRCT) is a rare variant of renal cell carcinoma that typically arises in a nonfunctional kidney. We report a case of CCPRCT in a 49-year-old Iranian male who presented with a mural nodule within a large cystic mass in his nonfunctional left kidney, and we discuss the relevant diagnostic challenges. Immunohistochemistry revealed diffuse and intense positivity for CK7 and carbonic anhydrase IX in a cuplike distribution, p53 positivity, and no expression of AMACR or CD10. Ki67 staining showed approximately 5% positivity in neoplastic cells. The differential diagnoses include clear cell and papillary renal cell carcinomas and papillary adenoma, all of which share overlapping clinical, imaging, histopathologic, and immunophenotypic features with CCPRCT. Accurate histological and immunophenotypic evaluation is crucial, as CCPRCT is clinically indolent, and correct diagnosis significantly influences patient outcomes and quality of life.
