Baseline Demographic, Medical Characteristics, and Quality-of-Life Scores of All HSNI Users and Current Study Participants

CharacteristicPhase 1 and 2 HSNI Users (n = 66)Current Study/Phase 3 Participants (n = 28)
HSNI = hypertonic saline nasal irrigation; RSDI = Rhino Sinusitis Disability Index; SIA = single-item assessment.
* Using a 30-item validated multidimensional disease-specific assessment instrument, participants scored their sinus symptoms: 0 = maximal impact of sinus symptoms on quality of life, 100 = no impact.
† Using a 1-7 Likert scale, where 1 = no impact, and 7 = maximal impact, participants responded to the statement: “Please evaluate the overall severity of your sinus symptoms since enrolled in the study.”
