Caries Score	Age	Sex	Race	Tooth-Brushing Frequency	Fluoride Intake
D2fs-total	+ (0.002/0.07)	+ (0.26/0.14)	+ (0.70/0.99)	− (0.02/0.07)	− (0.002/0.02)

^*: “+” represents positive association (risk) and “−” represents negative association (protective) between covariates and caries phenotype; Entries in the table are in the format as (p-value in linear/logistic regressions); significant P values are in bold; Males and Caucasians samples were set as reference groups when studying the sex and race effects respectively.
