Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Summed, Time-weighted Pain Intensity Difference From 0 to 24 Hours Postdose (SPID0-24)
Time Frame: From 0 to 24 hours post-dose
|
SPID0-24 was calculated by multiplying the pain intensity difference score at each post-dose timepoint by the duration (in hours) since the preceding timepoint and then summing these values over 0 to 24 hours.
Pain intensity was measured at baseline, 0.25, 0.5, 0.75, 1, 2, 3, 4, 5, 6, 8, 12, 16, 20 and 24 hours using the 4-point categorical pain intensity scale: 0 = none, 1 = mild, 2 = moderate, 3 = severe.
SPID0-24 can vary from -24 to 72.
The positive SPID value indicates improvement of pain relief.
The higher the SPID value, the more improvement of pain relief.

Measure Description |
Time Frame |
---|---|---|
Summed, Time-weighted Pain Intensity Differences (SPID)
Time Frame: 0-6, 0-8, 0-12, 0-16 and 16-24 hours postdose

Pain intensity was measured at baseline, 0.25, 0.5, 0.75, 1, 2, 3, 4, 5, 6, 8, 12, 16, 20 and 24 hours using the 4-point categorical pain intensity scale: 0 = none, 1 = mild, 2 = moderate, 3 = severe.
The total possible score ranges of SPIDs are SPID0-6: -6 to 18, SPID0-8: -8 to 24, SPID0-12: -12 to 36, SPID0-16: -16 to 48, SPID16-24: -8 to 24.
The positive SPID value indicates improvement of pain relief.
The higher the SPID value, the more improvement of pain relief.

Summed, Time-weighted Total Pain Relief Scores (TOTPARs)
Time Frame: 0-6, 0-8, 0-12, 0-16, 0-24, and 16-24 hours postdose
|
TOTPARs were derived by multiplying the pain relief score at each post-dose timepoint by the duration (in hours) since the preceding timepoint and then summing these values over the specified interval.
Pain Relief was evaluated at 0.25, 0.5, 0.75, 1, 2, 3, 4, 5, 6, 8, 12, 16, 20 and 24 hours postdose, using the 5-point overall pain relief scale: 0 = No relief, 1 = A little relief, 2 = Some relief, 3 = A lot of relief, 4 = Complete relief.
The possible total score ranges of TOTPARs are: TOTPAR0-6: 0 to 18, TOTPAR0-8: 0 to 24, TOTPAR0-12: 0 to 36, TOTPAR0-16: 0 to 48, TOTPAR0-24: 0 to 72, TOTPAR16-24: 0 to 24.
