A report on seven fetal cases associated with 15q11-q13 microdeletion and microduplication.

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
backgroundThe 15q11-q13 region contains three breakpoints (BP1 to BP3), and copy number variations often occur in the region.
aims15q11-q13 microdeletion and microduplication are usually associated with Prader-Willi and Angelman syndromes, respectively. It is not yet clear to what extent microdeletion and microduplication affect the physical health of the fetus and the child. In this study, we examined seven fetuses ranging in gestational age from 15 to 27 weeks. MATERIALS &
methodsDetailed prenatal screening and laboratory examinations were performed, while karyotype analysis and chromosomal microarray analysis (CMA) of the amniotic fluid and umbilical cord blood were applied for genetic analysis.
resultsCMA analysis showed that four fetuses harbored a microdeletion and one fetus showed a microduplication at 15q11.2 BP1-BP2, two fetuses had a microdeletion at 15q11-q13 BP2-BP3, and one fetus had an additional microdeletion at 16p13.11. DISCUSSION: There is no clear standard for the clinical diagnosis of 15q11-q13 microdeletion and microduplication, some of them have clinical phenotypes or are clinically affected.
conclusionTherefore, parents of such fetuses should be informed of the possibility of microdeletions or microduplications to mitigate the psychological burden, and medical consultation and assistance should be provided when communicating the results of the mid-gestation screening.
