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

introductionEndometriosis-associated intestinal tumors (EAITs) are rare malignancies that arise from ectopic endometrial tissue, and their clinical and molecular characteristics remain poorly defined. CASE PRESENTATION: We report a 53-year-old woman who presented with rectal bleeding. Imaging revealed a rectal mass invading the uterus. An initial endoscopic biopsy was inconclusive; however, a subsequent CT-guided biopsy confirmed adenocarcinoma. Immunohistochemical analysis suggested a gynecological origin. The patient underwent posterior total pelvic exenteration with bilateral lymphadenectomy. Histopathological evaluation confirmed endometriosis-associated endometrioid adenocarcinoma with ovarian metastasis. Postoperative chemotherapy was administered, and the patient has remained disease-free for 3.5 years.

conclusionsThis case highlights the diagnostic challenges and clinical complexity of EAITs. Tumor proteomic profiling provided additional biological insights and may serve as a reference for future comparative and translational research.
