-
↵a Breadth of expression was averaged over experiments in human and mouse for the human—mouse comparison, and was obtained from mouse only in the mouse—rat comparison.
-
↵b Pall is the number of equal or greater ρ in datasets obtained by randomly permuting all genes.
-
↵c Pgroup is the number of equal or greater ρ in datasets obtained by randomly permuting genes within classes of similar expression breadth.
