What researchers measure

Primary outcomes

  1. Total Nasal Symptom Score

    TNSS is a measure of nasal congestion, measured as the sum of four symptom scores for rhinorrhea, nasal congestion, nasal itching, and sneezing (using a scale of 0=None, 1=Mild, 2=Moderate, or 3=Severe). The minimum TNSS value is 0. The maximum TNSS value is 12. Lower TNSS score means a better outcome

    Time frame: 20 minutes

Secondary outcomes

  1. Visual Analog Scale (VAS) for Headache

    Visual Analog Scale (VAS) for Headache, using a scale of 0-10. 0 is the minimum and 10 is maximum on this scale. Lower scores mean a better outcome.

    Time frame: 20 minutes

  2. Visual Analog Scale (VAS) for Facial Pain

    Visual Analog Scale (VAS) for Facial Pain, using a scale of 0-10. 0 is minimum and 10 is the maximum value for this scale. Lower scores mean a better outcome.

    Time frame: 20 minutes
