Table 4. Adjusted Difference in Nasal Change Scores Relative to No Rhinitis^a.

Adjusted difference	Rhinitis, mean (95% CI) score
	Allergic	Nonallergic	No rhinitis
NOSE	14 (1 to 28)	7 (−4 to 18)	0 [Reference]
VAS	15 (0 to 30)	15 (3 to 28)	0 [Reference]

Abbreviations: NOSE, Nasal Obstruction Symptom Evaluation; VAS, visual analog scale.

^aAdjusted for age, sex, baseline nasal medications, oral antihistamine use, and baseline nasal congestion score (baseline NOSE score in NOSE change model and baseline nasal congestion VAS score in VAS change model). Data presented as adjusted difference in mean change (95% CI) using multivariate linear regression. Positive differences in mean change scores represent worse (or less improved) nasal congestion relative to the no rhinitis subgroup.
