Figure 3: Relationship between sinus symptoms and nasal lavage 8-isoprostane levels.

Figure 3:

a) In the STAN study, higher levels of nasal lavage were significantly associated with fewer sinus symptoms (SNOT 22 questionnaire), (Multiple regression adjusted for BMI and race, N=101, Adj R2=0.17, p=0.02), and b) in the EBAD study, higher levels of nasal lavage 8-isoprostane were associated with fewer sinus symptoms (Simple linear regression, N=29, r2=0.21, p= 0.02).
