Primary | Sum of Pain Intensity Difference (SPID) Using the Pain Intensity Visual Analog Scale (VAS) | Participants assessed pain intensity on a 100 mm visual analogue scale (VAS) with 0 meaning "no pain" and 100 meaning the "worst pain imaginable". The SPID VAS score for 0 to 12 hours following initial study drug dose measured the cumulative pain intensity difference during treatment with higher mean SPID VAS scores indicating greater improvement from Baseline. The SPID score is a measure of the cumulative pain intensity difference during treatment and the area under the curve was estimated using the linear trapezoidal rule. | From time of first study drug administration to 12 hours following first study drug administration | No |
Secondary | TOTPAR (Total Pain Relief) | TOTPAR was the time-interval weighted sum of pain relief. Pain relief was assessed by participants' responses to how their pain relief was compared with the pain they had just before receiving the first dose of study drug: no relief, a little relief, some relief, a lot of relief, or complete relief. Higher mean TOTPAR scores indicate better pain relief. The TOTPAR score is a measure of the cumulative pain intensity difference during treatment and the area under the curve was estimated using the linear trapezoidal rule. | From time of first study drug administration to 12 hours following first study drug administration | No |
Secondary | SPRID (Pain Relief and Pain Intensity Difference) | SPRID was defined as the sum of Pain Relief score (TOTPAR, See Outcome Measure 2 for details*) plus the Pain Intensity Difference (SPID) Categorical score, where participants assessed pain intensity on a Categorical Pain Intensity Scale by answering the following question: "My pain at this time is…" with one of the following responses: no pain or none, mild pain, moderate pain, or severe pain). Higher mean SPRID scores indicated better pain control. The SPRID score is a measure of the cumulative pain intensity difference during treatment and the area under the curve was estimated using the linear trapezoidal rule. | From time of first study drug administration to 12 hours following first study drug administration | No |
Secondary | Time to Perceptible and Meaningful Pain Relief | The median time (minutes) from first perceptible pain relief (onset of pain relief) and time until first meaningful pain relief. | From time of first study drug administration to 12 hours following first study drug administration | No |
