LN−, Lymph node negative; LN+, Lymph node positive; CI, Confidence intervals

Adjusted for age, gender, race, marital status, active-duty status, sponsor branch, year of diagnosis, tumour grade, tumour stage, number of lymph nodes examined and nodal status while the stratification variable (e.g. age) was not adjusted in the corresponding stratified analysis (e.g. stratified analysis by age). Chemotherapy was not adjusted for.
