1 · What the graph read from it

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.

2 · The registry

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

Introduction: Ureteral metastasis from endometrial carcinoma is extremely rare. We report a case identified at the time of the initial diagnosis of endometrial carcinoma. Case Presentation: A 64-year-old woman presented with suspected endometrial carcinoma. Contrast-enhanced computed tomography revealed hydronephrosis and a left ureteral mass suggestive of upper tract urothelial carcinoma (UTUC). Urine cytology showed malignant cells, but ureteroscopy was inconclusive. Because UTUC can affect management and prognosis, simultaneous surgery, including nephroureterectomy, was performed. Histopathological examination revealed ureteral adenocarcinoma morphologically similar to endometrial carcinoma. Immunohistochemical staining demonstrated PAX8 positivity, supporting the diagnosis of metastatic endometrial carcinoma. The final diagnosis was stage IVB endometrial carcinoma. Conclusion: Ureteral metastasis from endometrial carcinoma is extremely uncommon and may closely mimic UTUC on imaging, making preoperative diagnosis difficult.
