Notes:

(R): Reference category

(*): p < 0.05 compared to the Reference Category

(1): Poor oral health defined as having mean AL measure greater than median (>2.4 mm) and having mean DMFT score greater than median (>9)

(2): Adjusted Model is a full model, includes all covariates

(3): Adjusted Model is the most parsimonious model, includes only statistically significant covariates
