For ethnicity, we used the five major groups in Hawaii (Japanese, Caucasian, Hawaiian, Filipino, and Chinese). All other ethnicities were grouped into an \"Other\" category. The specific island of residence was coded in the HTR, but since close to 80% of the population resides on Oahu [25], we classified residence as either Oahu or non-Oahu. For marital status, we grouped all women who were identified as single, separate, divorced or widowed in the unmarried category. Women under age 50 were considered pre-menopausal and women 50 years and older were classified as postmenopausal. Tumor grade information from the HTR record was grouped into grade I (well-differentiated cells) vs. all other grades (II, III, IV and unknown).","divisions":[{"label":"Title","span":{"begin":0,"end":15}}],"tracks":[]}
