When smoking status and obesity were added (Model 6), the main effect of educational resources at 12 years of schooling remained negative and marginally significant (b = −0.017, 95% CI: −0.035, 0.002; p < 0.10), while the interaction term was attenuated and no longer statistically significant (b = −0.003, 95% CI: −0.008, 0.001). 3.2.5 Predicted differences across educational attainment levels Fig. 2 translates Models 5-6 into predicted differences in inflammation when comparing individuals educated in states at the 90th versus 10th percentile of educational resources, across levels of educational attainment (8, 10, 12, 14, and 16 years).
