Odds ratios shown. Models adjust for complex sampling design of NHIS; multiply-imputed models.

The 5 bolded coefficients identify instances of statistically significant difference (p<.05) across groups in the education-pain gradient, based on additional logistic models of pain with the same covariates as in Table 3 plus education-by-group interactions. The reference categories were HS for education and men, white, and 30–39 for the population subgroups, respectively. NH=non-Hispanic.
