Primary urethral carcinoma with variant histology: A case report and literature review.
Article in Molecular and clinical oncology, 2022. 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
Primary urethral carcinoma (PUC) has rarely been reported, notably with variant histology. The present case reports a 68-year-old male patient with a 3-month history of difficulty voiding urine accompanied by a burning sensation in the urinary tract and hematuria. Urethrography and computed tomography (CT) indicated a mass localized in the urethral bulb. A fine needle biopsy revealed the mass to be a malignant tumor of the urethra. Partial penectomy was eventually performed and postoperative histopathological examination confirmed that the lesion was PUC, with mixed characteristics of urothelial and squamous differentiation. The patient was postoperatively followed up and at 9 months, a repeat CT scan revealed local recurrence and metastases. The patient rejected further treatment and eventually succumbed to the disease three months later. The present case report demonstrates an example in which urothelial and squamous differentiation simultaneously exist in the pathological report. The clinical features, diagnosis and treatment status of PUC were also summarized and analyzed to improve the clinical understanding of this unique disease.
