Metabolomic Prediction of Pregnancy Viability in Superovulated Cattle Embryos and Recipients with Fourier Transform Infrared Spectroscopy
Table 2
Day 60 pregnancy and birth predictions on PCA transformed spectra data derived from metabolomic analysis of plasma recovered on Day 0 and Day 7 from recipients prior to transfer on Day 7 of embryos that had been cultured in vitro for 24 h in two laboratories (UNCEIA, France, and UTE-Bos, Spain).

: culture medium or plasma samples analyzed. Positive: samples that correspond to pregnancy/birth. Negative: samples that do not correspond to pregnancy/birth. : adjustable model parameter of -nearest neighbor classification algorithm. PCA: principal component analysis (+: applied; −: did not improve the results when applied). Day 7 plasma alone (not represented) yields <0.6 AUC. |
