^aIt excludes embryos with chaotic mosaicism, in which the individual chromosomes affected could not be distinguished.

^bIt includes individual chromosome pairs with mosaicism or aneuploidy.

^cChromosome pairs identified as diploid or mosaic/aneuploid on the both two NGS systems. Mosaic/aneuploid chromosome pairs with different aneuploid percentages on each system are also included.

^dChromosome pairs identified as diploid on the only one system, and as mosaic/aneuploid on the other system.
