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
rationaleOvarian tumor torsion is a critical gynecological emergency, predominantly affecting women of reproductive age, with benign teratomas being the most common culprits. In contrast, malignant ovarian tumors, such as mucinous cystadenocarcinoma, infrequently present with torsion due to their invasive and angiogenic characteristics. The occurrence of torsion in malignant tumors complicates diagnosis and management, particularly when associated with complications like congestion, infarction, and internal bleeding. This report details a rare case of primary ovarian mucinous cystadenocarcinoma presenting with acute torsion and significant internal bleeding. Our study highlights the diagnostic challenges and the urgent need for clear treatment guidelines, addressing an important gap in the existing literature regarding the management of torsion malignant ovarian tumors. By documenting this case, we aim to contribute to the understanding of this rare condition and provide insights that may help clinicians in similar scenarios. PATIENT CONCERNS: A 51-year-old postmenopausal woman presented with acute abnormal pain. Transvaginal ultrasound examination showed an 8-cm heterogeneous right ovary mass without ovarian blood flow on color Doppler. DIAGNOSES: Laparoscopy revealed torsion and rupture of the right ovarian tumor with 900 mL hemoperitoneum. The patient underwent right salpingo-oophorectomy complicated by continuous oozing and hematoma formation in the infundibular ligament. Unexpectedly, histopathology revealed a mucinous cystadenocarcinoma of the right ovary, pT1c2.
interventionThe patient underwent staging surgery and prophylactic hyperthermic intraperitoneal chemotherapy. OUTCOME: After 4 years of follow-up, no tumor recurrence or metastasis was found. LESSONS: Currently, there are no effective preoperative diagnostic and treatment guidelines for ruptured malignant ovarian tumors with torsion. The possibility of malignancy should be considered, and frozen section biopsy should be considered during surgery. Full detorsion before tumor resection to avoid incomplete pedicle coagulation and bleeding. Specimen removal by in-bag morcellation in minimally invasive surgery to prevent complications related to residual fragments of the specimen or dissemination of an occult malignancy.
