Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Combined Rhinoconjunctivitis Symptom and Medication Score
Periodo de tiempo: up to 6 weeks during the birch pollen season 2013
|
The efficacy analysis will be performed on the symptom and medication data collected from the first day of the birch pollen season as defined by pollen counts in the air in each site region (from March to May 2013 depending on site region), to 42 days later or to the end of the pollen season, whichever comes first. The scale range is from 0 to 3. Lower is the the RSMS value, better is the efficacy as this implies that lower is the symptoms and concomitant medication intake by the patient The RSMS includes 2 subscales : the Rhinoconjunctivitis Symptom Score (RSS) with a range of values from 0 to 3 and the Rhinoconjunctivitis Medication Score Score (RMS) with also a range of values from 0 to 3 The RSMS is the sum of the RSS and RMS divided by 2 |
