Figure 3 Implanting known implantation data (KID) embryos according to Z-score classification. Z1=zygotes having 3–7 polarized NPB; Z2=zygotes with homogeneously dispersed NPB; Z3=all the zygotes with a NPB distribution not included in groups 1, 2 or 4 (i.e.>7 polarized NPB, one PN polarized and the other dispersed or both dispersed but not homogeneously); Z 4=zygotes with only one or two NPB. Differences were not significant. Reproductive BioMedicine Online 2014 28, 475-484DOI: (10.1016/j.rbmo.2013.11.014) Copyright © 2013 Reproductive Healthcare Ltd. Terms and Conditions
