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
Background: Condition mediums have a potential role in oocyte development. In this study, we evaluated the effects of different mediums on the developmental potential of vitrified immature human oocyte after IVM and parthenogenesis by ionomycin. Methods: Immature oocytes were collected from 184 women after vitrification/thawing and maturation, in three types of IVM mediums separately. Finally, 151 IVM MΙΙ oocytes were obtained and randomly divided into six groups and underwent the following intervention. Fresh and vitrified-thawing MΙΙ oocytes were activated after IVM in three conditioned mediums by ionomycin. Mediums included 1) Minimum Essential Medium Alpha (α-MEM) (as control medium), 2) α-MEM supplemented with supernatants of Mesenchyme bone marrow (B.M), 3) α-MEM with ovarian growth factors (O.F). Then, scoring of parthenote embryos was undertaken in accordance with pertinent morphological properties. Moreover, the expression of Bax and Bcl2 were determined in the parthenote embryos. Result: Percentage of the degenerated oocyte, 2-4 cells, 4-8 cells, and 16 cells, was different in the experimental groups. Also, cytoplasmic maturation and blastocyst formation rates were significantly different ( Conclusion: Our findings indicate that the O.F. medium had more potent effects on oocyte growth and cytoplasmic maturation up to the blastocyst stage with the highest expression level of the BCL2 gene and the lowest relative amount of the BAX gene in this medium. The results of the present study have been verified only for parthenogenetically activated embryos, and any positive effect of the environment on the egg/embryo fertilized with sperm requires more extensive studies.
