Figure 2 The relationship between the percentage of live births in relation to increasing viability scores within compaction-stage and blastocyst embryos with the same morphological score, determined in the blinded analysis of 66 compaction-stage embryos (n=17 patients in the lower three quartiles; n=15 patients in the upper quartile) and 60 blastocysts (n=15 patients in each quartile).
