We have the following columns in the Enrichment results.
mt: The number of genes in the entire population annotated to this term
nt: The number of genes in the test set annotated to this term
mpat (Only “go” and “hierarchical”): The number of genes annotated to this term or parents of it in the entire population
npat (Only “go” and “hierarchical”): The number of genes annotated to this term or parents of it in the test set
pval: The naive p-value
padj: The p-value adjusted for multiple testing correction (pval -> padj) is Benjamini-Hochberg

* test statistics is the Parent-Child test (https://doi.org/10.1093/bioinformatics/btn250)
