Chromosome analysis of blastocysts derived from single pronuclear zygotes by array CGH and clinical outcomes by the transfer of single pronuclear zygotes.

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
purposeThis study aimed to explore the aneuploidy of blastocysts derived from single pronuclear (1PN) zygotes, almost 75% of which were regarded as diploid, using array CGH and examine the pregnancy outcomes.
methodsEmbryonic aneuploidy screening of sixteen embryos from 1PN zygotes and sixteen embryos from 2PN zygotes was performed using array CGH in study 1. In addition, the reproductive outcome of 1761 single blastocysts, after untested frozen-thawed blastocyst transfer in IVF/ICSI patients, was retrospectively analyzed and compared between the 1PN and 2PN groups in study 2.
resultsThe aneuploidy rates were 30.8% (4/13) in 1PN IVF, 33.3% (1/3) in 1PN ICSI, 46.2% (6/13) in 2PN IVF, and 100% (3/3) in 2PN ICSI. The 1PN group achieved clinical pregnancy in 25.0% (7/28) of IVF and 30.0% (3/10) of ICSI, whereas these rates in the 2PN control group were 44.6% (557/1250) of IVF and 37.4% (177/473) of ICSI. No miscarriage occurred in the pregnancies from 1PN zygotes, whereas the rates of miscarriage in the 2PN control group were 22.6% (126/557) in IVF and 22.2% (39/176) in ICSI. The delivery rate was similar in all groups. Ten deliveries in the 1PN group showed no newborn malformation.
conclusionWithin the limits of the small sample size, our results suggest that the aneuploidy and delivery rates of the blastocysts derived from 1PN zygotes are the same as those derived from 2PN zygotes. Blastocysts derived from 1PN zygotes may be used clinically and could increase the chance of pregnancy.
