Preferable correlation to blastocyst development and pregnancy rates with a new embryo grading system specific for day 3 embryos.
Article in Journal of assisted reproduction and genetics, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers.
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
purposeTo investigate the cleavage stage embryo quality by the correlation between the morphological features and blastocyst development rate to develop a new embryo grading system.
methodsA retrospective analysis, including 216 cycles of cleavage stage embryo transfer and 251 cycles of blastocyst transfer. The correlation with blastocyst development of the embryo cleavage stage, fragmentation and uniformity of blastomeres was evaluated.
resultsThere were significant differences in the blastocyst development rate between > or =7 cells and < or=6 cells (68.8% vs. 30.7%), <50% fragmentation and > or =50% fragmentation (51.9% vs. 25.7%), and evenly sized blastomeres and unevenly sized blastomeres (48.7% vs. 30.1%) on day 3. The new grading system defined by these 3 parameters showed a preferable correlation to the pregnancy rate.
conclusionsThe new grading system specific for day 3 embryos is useful for the selection of good quality embryos and may improve the pregnancy rate.
