A Comparison of the metabolite levels in spent culture medium (SCM) samples from successfully implanted embryos (n=23) and embryos that failed to implant (n=33) relative to the levels in the medium control samples (n=44). B) Principal component analysis (bi-plot) of the region-wise integrals of the three groups. Gray Inline graphic represents medium control, orange Inline graphic represents SCM from successfully implanted embryos, and blue Inline graphic represents SCM from embryos that failed to implant
