Age-stratified reference ranges for adenoid hypertrophy in children: a single-center retrospective study.

The prevalence of moderate hypertrophy ( A / N ratio 0.61–0.70) remained relatively stable, ranging from 34.9% to 37.4% among ages 1–9, before decreasing to 26.1% in the oldest age group; however, these variations did not reach statistical significance (all P > 0.05). 3.5 Sex-specific analysis of adenoid depth, nasopharyngeal depth measurements, A / N ratio and adenoid hypertrophy The analysis of AD, ND, A / N ratio, and AH stratified by sex and age groups ( n = 2,629) revealed no statistically significant differences ( Table 2 ).
