¹ n = number of genes in the analyzed dataset; m = number of genes in the original gene set

² Enrichment in degenerative embryo means significantly more genes in this gene set showed higher expression in degenerative embryos

³ Enrichment in blastocysts means significantly more genes in this gene set showed higher expression in blastocysts
