Prenatal diagnosis of 9p distal deletion associated with subependymal cysts: A case report and literature review.
Review in Medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
rationaleChromosome 9p deletions are frequently detected in postnatal cases presenting with diverse neurological symptoms. However, limited prenatal reports of these chromosomal disorders poses a challenge for genetic counseling during pregnancy. PATIENT CONCERNS: A pregnant woman underwent amniocentesis for cytogenetic analysis and a chromosomal microarray analysis (CMA) because of imaging findings indicating subependymal cysts. The prenatal phenotypes were reviewed on the basis of previous reports. DIAGNOSES: The fetal karyotype was 46,XN,del(9)(p22). The CMA showed a 16.65-Mb deletion in the 9p24.3p22.2 region.
interventionsAfter genetic counseling, the couple chose to terminate the pregnancy. OUTCOMES: Fetal growth restriction and a single umbilical artery are common ultrasound findings detected in 9p deletions. LESSONS: The prenatal genotype-phenotype of 9p deletion syndrome is complicated because of phenotypic diversity and incomplete penetrance. To offer better genetic counseling for such cases, ultrasonographic, cytogenetic, and molecular genetic results should be combined.
