Primary outcomes
- Time Weighted Sum of Pain Intensity Differences (SPID) in Sore Throat Pain Intensity Scale (STPIS) Over the 24 Hours Post-baseline (STPIS SPID24) — baseline (pre-dose), post-dose - hourly up to 24 hours
STPIS measures sore throat pain intensity on a 100-mm visual analog scale completed by participants. A mark at 0-mm indicates no pain upon swallowing and 100-mm indicates severe pain. SPID24 was calculated as the sum of the time weighted pain intensity differences from baseline until 24 hours. The full range was -104412 (complete pain relief within 1 hour of dosing that lasts 24 hours) to 27588 (maximum pain within 1 hour lasting 24 hours) using the mean baseline STPIS. Participants with a last recorded time point \<21 hours were considered Not Evaluable. If a participant used rescue medication, all post-rescue STPIS values in the 24-hour interval were assigned the baseline value for STPIS. Missing scores of STPIS with non-missing STPIS scores at earlier and later assessments were imputed using linear interpolation assuming the time of the missing assessment to be the nominal time since initial dose.
