Subgroup analysis according to the phenotype features, CRSwNP
and CRSsNP
For both phenotype features, CRSwNP and CRSsNP, the nasal irrigation had
a better
distribution of fluorescein with statistical significance, however the
effect size was greater in CRSsNP patients (CRSwNP; mean
difference=2.28, 95%CI:0.33-4.23, p -value 0.02 and CRSsNP; mean
difference=4.36, 95%CI:1.44-7.27, p -value 0.003).(Table
