1. General information
A total of 425 children were enrolled. The median age was 6 (IQR:3.5,8.5) years, and 60.5% were boys. The median BMI was 16.0 kg/m2 (IQR:14.9,18.0); 183 patients (43.1%) were diagnosed with OSAHS, including 113 patients (26.6%) with mild OSAHS, 70 patients (16.5%) with moderate to severe OSAHS, and 242 patients (56.9%) with non-OSAHS. A total of 52 patients (12.2%) had an A/N ratio ≤ 0.60, 77 patients (18.1%) had an A/N ratio from 0.61~0.70, 142 patients (33.4%) had A/N ratio from 0.71~0.80 and 154 patients (36.2%) had A/N ratio ≥0.80.
2. Demographic characteristics of patients with OSAHS and non-OSAHS
The A/N ratio was significantly higher in the OSAHS group than in the non-OSAHS group(Table1), and moderate-severe OSAHS patients had a higher A/N ratio than mild OSAHS and non-OSAHS patients(Table2). However, age, sex, BMI, and course of disease did not differ significantly between the OSAHS and non-OSAHS groups.
