Change From Baseline in Mean Average Score Using Pittsburgh Insomnia Rating Scale (PIRS) in Q1, Q3, Q17 and Q18 at Day 7
The PIRS questionnaire had 3 sections (Section A \[Q1 to Q12\], Section B \[Q13 to 16\] and Section C \[Q17 to Q20\]). The following questions were asked from Section A : 1. One or more awakenings after getting to sleep and 3 Sleep that does not fully refresh you, and Section C: 17 Your sleep quality compared to most people and 18 Your satisfaction with your sleep. Section A question were scored as follows: 0= Not at all bothered, 1= slightly bothered, 2=moderately bothered, and 3= severely bothered. Section B, Q13 and 14 were scored as follows 0= Less than ½ hour, 1= between ½ to 1 hour, 2= between 1 to 3 hours and 3=more than 3 hours or I didn't sleep; Q15 and 16 were scored as 0=more than 7 hours, 1= between 4 to 7 hours, 2= between 2 to 4 hours, and 3=Less than 2 hours or I didn't sleep. Section C questions were scored as follows: 0=Excellent, 1=Good, 2=Fair, and 3=Poor. Lower PIRS score shows better sleep quality.

Sleep problems (difficulty getting sleep, unable to get a good night sleep or wake up during the night, restless \[tossing and turning\] and having to get up because stuffy nose or to blow nose using the score, scores range: Min-Max \[0-24\]), Sleep time problems (Nasal congestion or stuffy nose, sinus pressure or pain, runny nose, post-nasal drip \[drainage down back of nose/throat\], and headache, scores range: 0-30); Symptoms on waking in the morning (Feel tired and unrefreshed, nasal congestion or stuffy nose, congestion in sinuses, takes time to clear nighttime drainage after waking up, scores range:0-24); practical problems (have to avoid symptom triggers (such as dust, cigarette smoke, strong smells and perfumes, need to rub nose or eyes, and have to take medication, scores range: 0-18). Lower scores indicate improvement in the rhinitis symptoms.
