  1. Model 1 includes only the educational attainment of directly connected social network members.
  2. Model 2 adds the educational attainment of indirectly connected (distance-two) network members.
  3. Model 3 adjusts for demographics such as age, household income, and marital status.
  4. Model 4 adjusts for health and health behaviors such as cognitive health, physical health, comorbidities, hypertension status, and smoking status.
  5. Model 5 is the fully adjusted model, incorporating all covariates and adding network size.
