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
purposeLarge ovarian tumors with a predominantly cystic pattern are uncommon in adolescents. This study evaluates the effectiveness of a decompression technique utilizing a balloon trocar to facilitate ovarian-sparing surgery, while preserving oncologic principles, in adolescent patients presenting with such lesions.
methodsA retrospective review of four consecutive cases managed by a single surgeon over a 7-year period ending December 2024. We describe the surgical technique of this innovative approach, and provide patient-specific clinical data including histopathologic findings and follow-up outcomes.
resultsThe median patient age was 13 years (range, 10-17), and the median maximum tumor diameter was 17 cm (range, 10-28). The balloon trocar technique enabled a tight seal and closed suction drainage of the tumor cyst fluid, facilitating safe decompression and exteriorization of the mass. All surgeries were completed with negligible morbidity. Histological examination revealed three mature cystic teratomas and one serous cystadenoma. At clinical and ultrasonographic follow-up ranging 8 months to 7 years (median, 6,5 years), all patients remained free of recurrence, maintained regular menstrual cycles with normal-sized preserved ovaries, and expressed high satisfaction with their cosmetic outcomes.
conclusionLarge predominantly cystic ovarian tumors are generally associated with a favorable prognosis. Preemptive in situ decompression using a balloon trocar represents a simple, effective, and rapid technique to minimize the risk of tumor spillage. This approach facilitates safe ovary-sparing surgery for these large tumors, while also providing excellent cosmetic outcomes.
