SECONDARY
Four secondary patient reported outcome measures were assessed:• SNOT-22 score at 12 months.• SNOT-22 subscale (nose, sleep, ear/facial pain, psychological) score at baseline, six months, and 12 months.• Score on the NOSE scale at baseline, six months, and 12 months.• General quality of life, measured at baseline, six months, and 12 months using the physical component scores and mental component scores of the 36 item Short Form survey (SF-36), which assesses recall over the preceding week, with higher scores indicating better quality of life.Secondary clinical measures at baseline, six months, and 12 months were:• The double ordinal airway subjective scale, which is a subjective comparator of right and left nasal patency,• Objective assessments of nasal patency after decongestant use, including peak nasal inspiratory flow, measured using a peak nasal inspiratory flow meter (GM Instruments, Kilwinning, UK).• An imbedded economic evaluation is to be reported separately in a future publication.
