Total staining score of fluorescein in all anatomical areas
The concordance correlation coefficient to determine the interrater
reliability for the
grading score was 0.98. The total staining score of fluorescein in all
anatomical areas in the nasal irrigation group was statistically more
significant than that of the nasal spray group, with a mean difference
score of 2.90, 95%CI:1.22-4.58, p -value 0.001.(Table 2)
