Birth of monozygotic dichorionic twins after a single blastocyst embryo transfer: a case report of genetic determination of zygosity.

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
Objective: To report a case of monozygotic dichorionic (DC) twins after a single cryopreserved blastocyst embryo transfer followed by genetic determination of zygosity postpartum. Design: Case report. Setting: University hospital. Patients: A 26-year-old woman with polycystic ovary syndrome and her 36-year-old male partner with severe oligozoospermia, resulting in a 1.5-year history of primary infertility. Interventions: Controlled ovarian stimulation and intracytoplasmic sperm injection treatment with single cryopreserved embryo transfer at blastocyst stage. Main Outcome Measures: Ultrasound images of the fetuses and short tandem repeat genotyping postpartum. Results: A DC twin pregnancy following a single cryopreserved blastocyst embryo transfer was confirmed at the first trimester screening. Confirmatory testing performed postpartum included short tandem repeat analysis determining monozygosity and pathology examination reporting DC placental configuration. Conclusions: Dichorionic monozygotic twins are thought to arise from the splitting of an embryo before the blastocyst stage. This case suggests that placental configuration of monozygotic twins may not strictly depend on timing of embryo division. Genetic analysis is the only tool to confirm the zygosity.
