Intervention not reported

Early embryo transfer ‐ GM501 (specific) versus ISMI (other) · Women in assisted reproductive technology cycles (ART) receiving human pre‐implantation embryos in either early (cleavage stage transfer)…

It is very uncertain whether the intervention changes early embryo transfer ‐ GM501 (specific) versus ISMI (other) (very low certainty).
