Primary large cell neuroendocrine carcinoma of the bladder: A case report.
Article in World journal of clinical cases, 2024. 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
backgroundLarge cell neuroendocrine carcinoma (LCNEC) of the bladder is a rare non-urothelial tumor of the bladder. The treatment of LCNEC of the bladder is different from that of urothelial carcinoma (UC); therefore, early and accurate diagnosis is particularly important. As LCNEC of the bladder is rare and its clinical symptoms and radiographic features are similar to those of urothelial tumors, the clinical diagnosis of the disease remains challenging. CASE SUMMARY: We report a 72-year-old female patient who presented with gross hematuria for 3 mo. A solitary tumor located in the anterior wall of the bladder was found by cystoscopy. Pathological examination after biopsy suggested UC of the bladder in the absence of immunohistochemical assessment. The patient underwent partial cystectomy and was finally diagnosed with LCNEC (pT2bN0M0) based on the results of postoperative immunohistochemical examination. During the 10-mo follow-up, no signs of tumor recurrence or metastasis were found.
conclusionImmunohistochemical examination is essential for diagnosing LCNEC of the bladder. Accurate diagnosis and multidisciplinary treatment in the early stage of the disease are crucial for improving the prognosis.
