Participant flow and baseline characteristics
Forty patients were enrolled in the study. However, two patients were
excluded due to a
history of previous sinus surgery. Thirty-eight patients were randomized
to receive nasal irrigation (n=19, 38 sides) or nasal spray (n=19, 38
sides). Five sides of the nasal cavity were excluded for data analysis
due to significant perioperative bleeding. Finally, there were 19
subjects with 36 sides in the nasal irrigation group and 19 subjects
with 35 sides in the nasal spray group for the intention-to-treat
analysis.(Figure 2) Of these 38 participants, the baseline
characteristics were balanced between two groups, as shown
in Table 1 .
