NOTE:

^*Low expression of ER and PR denotes negative, weak or moderate expression (SI = 0-8); high expression of ER and PR denotes strong expression (SI = 9-12).

^**Low expression of Ki-67 denotes ≤ 30% positive cells and high expression denotes > 30% positive cells.

^***Missing numbers denote samples that were damaged and could not be evaluated.
