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
Case: A 23-year-old nulligravida with bilateral ovarian fibromatosis, amenorrhea, and severe ovulatory dysfunction was diagnosed via laparoscopic biopsy. As pregnancy was desired but transvaginal oocyte retrieval was not feasible due to dense fibrosis, partial ovarian resection was performed, and oocytes were obtained using ovarian tissue oocyte in vitro maturation (OTO-IVM). Outcome: In the first OTO-IVM cycle with human chorionic gonadotropin (hCG) priming, 11 mature and 63 immature oocytes were retrieved. Mature oocytes underwent intracytoplasmic sperm injection (ICSI), whereas immature oocytes were cultured in vitro for maturation before ICSI. A total of 13 oocytes were fertilized, five embryos were cryopreserved, and one embryo transfer resulted in a biochemical pregnancy. At age 28, a second OTO-IVM using dibutyryl-cyclic AMP (dbcAMP)-enhanced biphasic IVM produced seven germinal vesicle oocytes; three matured to metaphase II, two fertilized, and one cleavage-stage embryo led to a live birth at 39 weeks of gestation. Conclusion: This is the first documented live birth following dbcAMP-enhanced biphasic IVM of ovarian tissue-derived oocytes. These findings suggest that dbcAMP-enhanced biphasic IVM may be a feasible option when granulosa cell support is limited, offering a potential addition to fertility preservation strategies.
