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)
