Embryo cell number on Day 7 and gene expression data were therefore log-transformed for analysis. A significant weak relationship was present between Day 7 progesterone and embryo cell number on Day 7 (R2 = 0.08; P = 0.01; Supplemental Figure S11; https:// doi .org/ 10 .3168/ jds .2017 -14306). However, BCS (P = 0.8), BCS change (P = 0.4), and DPP (P = 0.5) had no significant effects on Day 7 embryo size. A multivariate analysis indicated no effect of grade (1, 2, and 3) on the gene expression profile (P = 0.1). A multivariate analysis indicated no significant effects of Day 0 progesterone (P = 0.2), Day 7 progesterone (P = 0.5), BCS (P = 0.6), and DPP (P = 0.6) on the gene expression data (81 genes with gene expression greater than the limit of detection of the assay).
