Respiratory Syncytial Virus (RSV) Lower Respiratory Tract Disease (LRTD) Symptoms as Assessed by Respiratory Infection Intensity and Impact Questionnaire (RiiQ) Symptom Scale Score at Baseline |
RSV LRTD symptoms (cough, short of breath, wheezing, coughing up phlegm [sputum]) as assessed by the RiiQ symptom scale score at baseline were reported. The RiiQ symptom scale was a 13-items questionnaire rated on a 4-point scale. Each symptom was rated on a scale of 0 to 3 where 0=None, 1=Mild, 2=Moderate, and 3=Severe. Higher scores indicated greater severity. The LRTD symptom score was calculated as the mean of the LRTD symptom scores. |
