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
Background: Ovarian germ cell tumors are the most common ovarian malignancies in children. Because these patients have a notable risk of developing metachronous bilateral tumors or recurrences, maximizing the preservation of ovarian tissue during initial surgery is critical to protecting future fertility and endocrine function. Objective: A previously healthy 8-year-old girl underwent emergency laparotomy for ovarian torsion, resulting the right oophorectomy, with histopathology confirming a mature teratoma. Sixteen months later, a contralateral ovarian mass was detected and treated with ovarian-sparing excision, also diagnosed as a mature teratoma. At age 10 (10 months after the second excision), she was found to have an 8 cm pelvic tumor and elevated Conclusions: The presented case highlights a disadvantage of overzealous oophorectomy. Detorsion of the seemingly necrotic ovary followed by second-look surgery could have preserved some ovarian function.
