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
objectivesTo explore and correlate the ultrasonic, clinical, and pathological characteristics of malignant ovarian tumors in children for early diagnosis and pathological typing.
methodsA retrospective analysis was performed on the ultrasonic examination results, clinical data, and laboratory indicators of 49 cases of pathologically confirmed malignant ovarian tumors in children from January 2020 to December 2024.
results(1) Pathological types: Germ cell tumors accounted for 75.5% (immature teratoma 59.5%, endodermal sinus tumor and mixed germ cell tumor each 16.2%), sex cord-stromal tumors accounted for 16.3%, and lymphoma accounted for 8.2%. (2) Ultrasonic characteristics: Tumors were predominantly large (>10 cm, 73.5%), solid (51.0%), with irregular contours (81.6%), calcification (57.1%), and high-risk ovarian-adnexal reporting and data system (O-RADS) 4-5 (98.0%). (3) Significant differences were observed among different pathological types: Germ cell tumors were mostly unilateral, large-sized, and accompanied by calcification, with significantly elevated alpha-fetoprotein (AFP); sex cord-stromal tumors were solid without calcification, and 37.5% were associated with precocious puberty; lymphoma was predominantly bilateral, small-sized, and solid, with elevated lactate dehydrogenase (LDH). (4) Clinical features: Pubertal patients accounted for 32.7%; the primary presenting symptoms were abdominal pain/distension (55.1%).
conclusionsChildhood malignant ovarian tumors are predominantly germ cell tumors, manifesting as large, solid-predominant, calcified lesions with high-risk ultrasound features. Ultrasonic, clinical, and laboratory features vary significantly by pathological type. Integrating these characteristics (including O-RADS and tumor markers) enables preoperative pathological diagnosis, supporting early multi-dimensional and personalized management.
