Délai: 0 to 8 hours
SPRID: time-weighted sum of pain relief rating combined with pain intensity difference (PRID) over 8 hours. SPRID 0-8 score range: -8 (worst) to 56 (best). PRID: sum of Pain intensity differences (PID) and pain relief rating (PRR) at each time point. PRID score range: -1=worst to 7=best. PID: baseline pain severity score minus pain severity score at a given time point (pain severity score range 0=none to 3=severe; baseline score range 2=moderate to 3=severe). PID score range: -1(worst) to 3 (best). PRR: assessed on 5-point pain relief rating scale (0=No relief to 4=Complete relief).
0 to 8 hours
Time to Onset of Meaningful Relief
Délai: 0 to 8 hours
Participants evaluated the time to meaningful relief by stopping a second stopwatch labeled 'meaningful relief' at the moment they first began to experience meaningful relief. Stopwatch was active up to 8 hours after dosing or until stopped by the participant, or rescue medication was administered.

Délai
Time to Confirmed First Perceptible Relief
Délai: 0 to 8 hours
Participants evaluated the time to first perceptible relief by stopping a stopwatch labeled 'first perceptible relief' at the moment they first began to experience any relief.

PID was derived by subtracting the pain severity score at a given post-dosing time point (pain severity score range 0 [none] to 3 [severe]) from the baseline score (Baseline pain severity score range 2 [moderate] to 3 [severe]). Total possible score range for PID: -1 (worst) to 3 (best). PRR was assessed on 5-point categorical pain relief rating scale (0=No relief to 4=Complete relief).
