Clinical and guardian-reported measures of child oral health in the ZOE 2.0 study sample, and associations with reported child oral health status.

^*Participants with clinical information only are included in ECC and unrestored disease comparisons, whereas all participants with non-missing questionnaire information are included in the toothache history comparison.

^†Defined at the ICDAS≥3 caries lesion detection threshold.

^‡Prevalence ratio and 95% confidence intervals estimated with an unadjusted log-binomial model accounting for the complex study design using Stata's svy function.

^||Adjusted average marginal effect (expressed in percentage points) of the association of reported child oral health status, with ECC, unrestored disease and history of toothaches, estimated from an adjusted multilevel generalized linear model including terms for features of study design, as well as children's age, race/ethnicity, and guardian's education.

ECC, early childhood caries; PR, prevalence ratio; CI, confidence interval; A.M.E., average marginal effect.
