Values are odds ratios and [95% confidence intervals]. All models are also adjusted for individual age in years and sex, and for school region, urbanicity and public/private school type.
All odds ratios are for comparisons with White non-Hispanics in the richest income quintile. Cells containing en-dashes represent categories with insufficient numbers of cases to allow estimation.
