Table 1.

Total Nasal Symptom Scores (TNSS) Each symptom (sneezing, congestion, itching, and rhinorrhea) is graded from 0-3 by the participants during the screening and NAC visits

Score	Symptoms
0=None	No symptoms evident
1=Mild	Symptom present but easily tolerated
2=Moderate	Definite awareness of symptom; bothersome but tolerable
3=Severe	Symptom hard to tolerate; interferes with daily activity

The Nasal symptoms are then added for each time points to reach the TNSS.
