Supplemental Table 2: Age-adjusted odds ratios (ORs) and 95% confidence intervals
(CIs) for the associations between postmenopausal recreational physical
activity (RPA) and ER+PR+ breast cancer (vs. ER-PR- breast cancer) considering
the GSTP1 methylation status of the tumor (methylated vs. unmethylated),
the Long Island Breast Cancer Study Project (1996-1997).
