Association between age at thelarche and incident breast cancer stratified by Bayesian family history score. N = 49,503 women. Median Bayesian family history score (BFHS) is 0.3076. Estimates are adjusted for attained age, race/ethnicity, and family income level growing up and stratified by birth cohort. p for heterogeneity by BFHS is 0.19 for categorical age at thelarche and 0.06 for continuous age at thelarche. Hazard ratios (HRs) and 95% confidence intervals (CIs) are plotted on the log scale
