FIGURE 2.

Flowchart of sample processing success and loss. In total, 212 of 218 blastocysts were fully re-expanded. Blastocentesis failed in 38 full-expanded blastocysts. No valid sequencing data (low reads number) were generated in an additional 26 blastocysts. Inner cell mass was available as a reference for 89 blastocysts, and whole embryo was used as a reference for the remaining 59 blastocysts. Among the 148 blastocysts with both SCM and BF data, 101 were euploid, and the remaining 47 were aneuploid.
