*Adjustment sets for regression analyses were derived by application of directed acyclic graphs (more details—including the graphs—have been published together with the analysis protocol https://osf.io/ycz7n).
†Univariate logistic regression model: no adjustment is necessary or possible—as it would produce a collider bias—to estimate the total effect of the independent variable on the outcome.
‡Multivariable logistic regression model adjusted for the variable: migration background.
§Multivariable logistic regression model adjusted for the variables: sex, age, educational attainment, migration background.
¶Entered as a continuous variable in regression analyses (range from 0 (€0 income) to 7 (€7000 or more).
**Multivariable logistic regression model for the variables: age, educational attainment, income per person, migration background, cohabitation.
††Multivariable logistic regression model for the variables: age, educational attainment, income per person, migration background, region of residence.
