Power to detect genetic association as a function of genotype relative risk (GRR) and disease allele frequency, at a significance level of 0.001, for the phenotype of "any dental caries in the permanent dentition". B. Power to detect genetic association as a function of genotype relative risk (GRR) and disease allele frequency, at a significance level of 0.001, for the phenotype of "no dental caries in the permanent dentition".
