  1. # Indicates the relative proportion of caries-affected primary teeth of a given morphology among all caries-affected primary teeth. a Chi-square test. Confidence interval calculation: use of the Clopper-Pearson exact method (binomial distribution). In the table, the effect size for the chi-square test is reported using Cramer’s V. The calculated Cramer’s V value of 0.29 indicates a weak association.
