Ranking into caries quintile groups was for caries prevalence at follow-up by sex and 10-year age groups. Hence, age and sex was not included in the adjusted logistic regression analysis model
aadjustment for marital status, additional lifestyle measures, and medical measures had no further effect (cf. Additional file 2: Table S3)
