| No natural teeth | 1.69 (1.21; 2.35) |
aRate ratio of being UNAWARE of mouth cancer estimated from Cox regression model adjusted for age. All variables are in the same model. For example, participants with no natural teeth were 1.69 times more likely to be UNAWARE of mouth cancer compared to those who have 20 or more natural teeth.
