TABLE 2.

Analysis of implantation and pregnancy rates for two populations of patients with blastocyst transfer suggest a correlation between time-lapse markers used by Eeva and implantation and pregnancy outcomes.

Patient population No. of patients No. of embryos Age (y) Implantation rate Clinical pregnancy rate Ongoing pregnancy rate
At least 1 Eeva High transferred 47 89 32.1 ± 5.2 49% (44/89) 60% (28/47) 55% (26/47)
Only Eeva Low transferred 30 52 32.2 ± 5.1 21% (11/52) 40% (12/30) 37% (11/30)
P value .9 <.001 .09 .11

Note: Eeva High versus Low denominations are based on whether time-lapse markers P2 and P3 are within defined time windows (9.33 ≤ P2 ≤ 11.45 hours and 0 ≤ P3 ≤ 1.73 hours).
