Stratum-specific estimates for the odds of current smoking among women with versus without past year MDE, adjusted for age, education, income, marital status, race, and calendar year (categorical). The model producing estimates stratified by respondent’s other children in the home was additionally adjusted for the respondent’s other children in the home.
P-values for heterogeneity between stratum-specific odd ratios and the odds denoted as the referent for each demographic characteristic. Assessed based on demographic characteristic × MDE product terms.
