(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
