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
purposeReporting a rare viable delivery of a 45,X/46,XY mosaicism female with complete gonadal dysgenesis (CGD) after receiving hormone replacement therapy (HRT), oocyte donation, and overcoming multiple pregnancy complications.
methodsAn infertile female presenting with primary amenorrhea was recruited. Comprehensive genetic evaluation including SRY and AZF gene testing, chromosome karyotyping, fluorescence in situ hybridization (FISH), CNV-seq, and whole-exome sequencing (WES) was performed. This patient was treated with HRT and oocyte donation and received appropriate treatment during pregnancy.
resultsThe patient showed a hypoplastic uterus and absent bilateral ovaries via ultrasound detection. She was identified to be a 45,X/46,XY mosaicism through CNV-seq analysis of peripheral blood, saliva, urine, and buccal cells. And further gonadal pathology further confirmed a diagnosis of CGD. Following successful management of multiple pregnancy complications, she delivered a healthy full-term infant.
conclusionsThis is the second case around the world and the first case in China of 45,X/46,XY mosaic female with CGD who experienced a successful pregnancy via occytes donation.And we provided a detailed examination and treatment process for a series of complications in this case, especially the management of threatened miscarriages and preterm labour.
