  1. DET-3 M = patients receiving two day 3 embryos selected by IMCS; DET-3 ME = patients receiving two day 3 embryos selected by standard morphology plus Eeva™ score; SET-5 M = patients receiving one day 5 blastocyst selected by IMCS plus blastocyst morphological score; SET-5 ME = patients receiving one day 5 blastocyst selected by blastocyst morphological score plus Eeva™. Data are expressed as absolute value and percentage. * Significance is referred to the comparison of DET-3 M vs. DET-3 ME, SET-5 M and SET-5 ME
