Factors associated with adenoid regrowth as determined by DISE.

Variable	Regrowth	Absent/mild adenoid	value
Males/females, %	60.0/40.0	64.5/34.5	0.73
Diagnosis of allergic rhinitis, %	56.0	38.7	0.20
Diagnosis of asthma, %	40.0	32.3	0.55
Diagnosis of behavioral issues, %	20.0	41.9	0.08
Diagnosis of developmental delay, %	20.0	35.5	0.20
Diagnosis of reflux, %	32.0	32.3	0.98
Initial Adenoid Size, Grades 0–4 (mean ± 95% CI)	2.77 ± 0.42	2.23 ± 0.33
BMI percentile, groups 1–4 per Table 1 (mean ± 95% CI)	3.28 ± 0.39	2.56 ± 0.42
Prior surgery adenoidectomy only, %	8.0	22.6	0.14
coblation technique, %	8.0	22.6	0.14
Age at adenoidectomy, mean ± 95% CI	5.12 ± 1.04	5.55 ± 1.52	0.31
