Relationship between plasma progesterone (P4) concentrations on day 4 after estrus and A: the expression of the top 30 most significant DEGs at the luminal epithelium, according to the ten-percentile classes of progesterone concentrations; B: the pregnancy per embryo transfer according to the ten-percentile classes of progesterone concentrations; C and D: the expression of the two DEGs with the greatest positive and negative correlation coefficient (r). DEGs, differentially expressed genes.
