Summed, Time-weighted Pain Intensity Difference From 0 to 24 Hours Postdose (SPID0-24) [ Time Frame: From 0 to 24 hours post-dose ] [ Designated as safety issue: No ]
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.

  • Summed, Time-weighted Pain Intensity Differences (SPID) [ Time Frame: 0-6, 0-8, 0-12, 0-16 and 16-24 hours postdose ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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.
  • Pain Intensity Differences (PIDs) by Time From Initial Dose [ Time Frame: At 0, 0.25, 0.5, 0.75, 1, 2, 3, 4 ,5 ,6, 8, 12, 16, 20 and 24 hours postdose ] [ Designated as safety issue: No ]
    Pain intensity was evaluated using a 4-point Categorical Pain Intensity Rating Scale: 0 = none, 1 = mild, 2 = moderate, 3 = severe
  • Pain Relief From Initial Dose [ Time Frame: At 0.25, 0.5, 0.75, 1, 2, 3, 4 ,5 ,6, 8, 12, 16, 20 and 24 hours postdose ] [ Designated as safety issue: No ]
    Pain Relief was evaluated 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
  • Median Time to First Intake of Rescue Medication [ Time Frame: Up to 24 hours postdose ] [ Designated as safety issue: No ]
    Time to first use of rescue medication was estimated using Kaplan-Meier method and analyzed by a logrank test stratified by baseline pain intensity. If at least 50% of subjects in a treatment group took rescue medication, the median time to first rescue was determined for that treatment group.
  • Cumulative Percentage of Participants Who Took Rescue Medication [ Time Frame: At 0.25, 0.5, 0.75, 1, 2, 3, 4 ,5 ,6, 8, 12, 16, 20 and 24 hours postdose ] [ Designated as safety issue: No ]

    Global assessment of investigational product as a pain reliever was rated on a 5-point categorical scale: 0 = poor, 1 = fair, 2 = good, 3 = very good, 4 = excellent
  • Summed, time-weighted pain intensity difference [ Time Frame: 0-6, 0-8, 0-12, 0-16 and 16-24 hours postdose ] [ Designated as safety issue: No ]
