Notes. Each paired comparison within age categories—node positive vs unstaged or Canada–USA comparisons that used Hawaiian vs other US samples—was significantly different (z), P < 0.05. Each paired comparison between age categories (e.g. node positive breast cancer among women ≥25 years of age vs node positive breast cancer among women <65 years of age) was significantly different (z), P < 0.05.
