Table 4. Age-specific craniofacial patterns of the children with snoring and ATH obtained by cluster analysis.

Data are reported as mean ± standard deviation or the frequency of expression.

Cluster 1 included patients aged 5–8 years with a skeletal Class I (C I) or Class II (C II) and hyperdivergent pattern; cluster 2 included patients aged 9–12 years with a skeletal Class II and hyperdivergent pattern; and cluster 3 included patients aged 7–8 years with a skeletal Class III (C III) and hyperdivergent pattern.

Normo, Normodivergent; Hypo, hypodivergent; Hyper, hyperdivergent.

^*Significant frequency representing the characteristic pattern in each cluster, analyzed by Pearson's chi-square test (p < 0.001).
