Notes. OR = odds ratio, CI = confidence interval. All effects were age and stage-adjusted across these categories: 25–44, 45–54, 55–64, 65–74 and 75 or older; and node positive or node negative breast cancer. Bolded ORs were statistically significant at p < .05.
a Null interaction was removed from the full model. *p < 10.
