Outcome Measures
Primary Outcomes (6)
Secretion Self-Rating Analog Scale score.
The overall score is analysed as the primary endpoint. Each sub-score is analysed independently in the secondary endpoints. This 40 point score is calculated as the sum of 4 criteria, each scored on 10 points. Analog scale from 1 to 10 on the frequency of secretions (from never to all the time) Analog scale from 1 to 10 on the colour of secretions (from clear to yellow) Analog scale from 1 to 10 on the quantity of secretions (from minimal to profuse) Analog scale from 1 to 10 on the viscosity of secretions (from liquid to very thick)
Before first treatment period of 14 days

This 40-point score is calculated as the sum of 4 criteria, each scored on 10 points. Analog scale from 1 to 10 on the frequency of secretions (from never to all the time) Analog scale from 1 to 10 on the colour of secretions (from clear to yellow) Analog scale from 1 to 10 on the quantity of secretions (from minimal to profuse) Analog scale from 1 to 10 on the viscosity of secretions (from liquid to very thick)
