Zinner Syndrome: An Incidental Finding.
Article in Cureus, 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
The authors present a case of a 56-year-old man referred to the urology clinic after an incidental finding on abdominal ultrasound. Imaging revealed an oval cystic lesion adjacent to the right seminal vesicle, initially interpreted as a probable atrophic ectopic kidney. Magnetic resonance imaging (MRI) confirmed right renal agenesis, ipsilateral seminal vesicle cyst, and probable ejaculatory duct obstruction. A small intralesional nodular component was identified. The patient was asymptomatic, with preserved renal function and a prostate-specific antigen of 0.9 ng/mL. A transrectal biopsy was performed due to the suspicious nodule. Histopathological analysis demonstrated seminal vesicle/ejaculatory duct tissue with stromal edema lined by a single-layer cuboidal epithelium (CK7+, 34BE12+, PAX8+, PSA-, CK20-) and low Ki-67 (<1%), with no evidence of malignancy. Conservative management with imaging surveillance was adopted. Follow-up MRI at six-month intervals showed lesion stability. The patient remains asymptomatic, emphasizing the role of imaging in the diagnosis, assessment, and monitoring of asymptomatic Zinner syndrome.
