a) The mini RQLQ total score is significantly increased in the persistent untreated nonallergic rhinitis (NAR) patients compared both to control normal subjects (NS) and the persistent NAR patients under regular treatment with nasal glucocorticoids (NAR + GC), without any significant difference between control subjects and persistent NAR patients under regular treatment with nasal glucocorticoids. b) The nasal symptoms score of the mini RQLQ is significantly increased in the persistent untreated NAR patients compared both to NS and NAR + GC, without any significant difference between control subjects and persistent NAR patients under regular treatment with nasal glucocorticoids. c) The interference of rhinitis pathology with the daily activities score of the mini RQLQ is significantly increased both in the persistent untreated NAR patients and NAR + GC compared with NS, without any significant difference between both groups of persistent NAR patients
