*) National is based on all the claims records from Achmea for dental practices with more than 50 young patients that are insured by Achmea.

The differences in FM-score between the dental practices were statistically significant (p < 0.01, Kruskal-Wallis test). Overall, differences in FM-score between the different socioeconomic groups were statistically significant (p < 0.01, Kruskal-Wallis test). The FM-score is lower for children and adolescents in the highest socioeconomic group compared to the middle and low groups. Differences in FM-score between age groups were not considered clinically relevant.
