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

Ovarian carcinosarcoma typically comprises high-grade carcinoma and sarcoma components. We report a case of a woman in her 40s with endometriosis-associated ovarian carcinosarcoma exhibiting an unusual presentation of well-differentiated adenocarcinoma and rhabdomyosarcoma. The patient underwent bilateral salpingo-oophorectomy and hysterectomy for tumors in both ovaries. Histologically, with a background of endometriosis, the epithelial component exhibited features of a borderline tumor with an intraepithelial carcinoma composed of Müllerian-type epithelium in both ovaries. In the left ovary, a very minor area of clear cell carcinoma (less than 5%) was identified. In contrast, the mesenchymal component was a well-differentiated rhabdomyosarcoma resembling fetal rhabdomyoma, constituting more than 60% of the left ovarian tumor. One year later, pulmonary metastases of the sarcomatous component were detected. Molecular analysis using next-generation sequencing identified
