Data are presented as mean or as number (%). Mann-Whitney U test (2-tailed) was used for continuous variables and McNemar-Bowker test was used to assess significant changes of percentage. p < 0.05 indicates significant difference between 2 groups. * p<0.05 (Compared to Pre-FESS value); SNOT-22 = the 22-Item Sino-nasal Outcome Test; VAS = Visual Analogue Scale; FESS = functional endoscopic sinus surgery. Data are presented as mean or as number (%). Mann-Whitney U test (2-tailed) was used for continuous variables and McNemar-Bowker test was used to assess significant changes of percentage. p < 0.05 indicates significant difference between 2 groups. * p<0.05 (Compared to Pre-FESS value); SNOT-22 = the 22-Item Sino-nasal Outcome Test; VAS = Visual Analogue Scale; FESS = functional endoscopic sinus surgery.
