Path diagram corresponding to a structural equation model used to examine the contributions of socioeconomic position (SEP) and reproductive factors (RPF) to the racial/ethnic disparities in the prevalence of estrogen/progesterone receptor (ER/PR)–negative breast cancer, Breast Cancer Care in Chicago Study, 2005–2008. RPF is a single variable that combines parity and age at first birth. SEP is a single variable that combines income, educational level, census tract disadvantage, and census tract affluence.
