Separation of frozen embryos cultured in BSA by sparse partial least square-discriminant analysis (sPLS-DA) (A,C,E) and by orthogonal partial least square-discriminant analysis (OPLS-DA) (B,D,F) measured by gestational endpoints Day-40, Day-62 and birth, respectively. Figure 3B, Q2: p < 0.06, R2Y: p < 0.03. Figure 3D: Q2: p < 0.07, R2Y: p < 0.04. Figure 3F: Q2: p < 0.03, R2Y: p < 0.01. Empirical p-values were obtained after 100 permutations.
