Neonatal outcomes after the implantation of human embryos vitrified using a closed-system device.
Article in Journal of assisted reproduction and genetics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
purposeClosed vitrification poses a risk of adversely affecting embryo development, while it may minimize the risk of contamination. We assessed the effects of closed-system human embryo vitrification on fetal development after implantation, neonatal outcome, and clinical safety.
methodsThis was a retrospective cohort study conducted at a private fertility clinic. A total of 875 vitrified-warmed blastocysts that were single-transferred under hormone-replacement cycles between November 2011 and December 2013 were randomly divided into two groups (closed vitrification, n 313; open vitrification, n 562) after receiving the patients' consent forms. Developmental competence after implantation, including gestational age, birth weight, sex, Apgar score, and anomalies of newborns, after the transfer of blastocysts vitrified by closing vitrification was compared with that obtained in the case of open vitrification.
resultsThere were no significant differences between the use of closed and open vitrification systems in embryo development after implantation, gestational age, birth weight, sex ratio, Apgar score, and congenital anomalies of newborns.
conclusionHuman embryos can be vitrified using a closed vitrification system without impairment of neonatal development.
